Abstract: Ester-functionalized long-chain pyridinium salt 1-(2-(dodecyloxy)-2-oxoethyl)pyridin-1-ium chloride (1b) has been
synthesized. The influence of the substance on morpho-physiological traits of wheat seedlings (germination, shoot and root length and
biomass, chlorophylls and carotenoids content, as well as flavonoid content) has been studied. The germination of seeds increased after
their exposure to water solutions of pyridinium chloride 1b in the concentration range 0.001-0.1%. However, the concentration 0.1% has a
negative effect on plant growth leading to reduced growth parameters in shoots and roots, plant mass, as well as pigments content. The
exposure of wheat seeds to water solutions of pyridinium salt with lower concentrations (especially at 0.001%) significantly increased
shoot and root length, as well as wet green mass in 7-day-old seedlings. At a concentration of 0.01%, the substance caused a significant
increase of chlorophyll a, chlorophyll b, and carotenoids content thus revealing a positive effect on the photosynthetic apparatus of plant
leaves. The flavonoid content in a green part of the plants also significantly increased which may indicate activating the plant defense
system under mild stress conditions. The high growth-promoting effect of long-chain pyridinium chloride 1b on wheat plants, together
with its broad range of antimicrobial activity and biodegradability, makes it an attractive product for various agrochemical applications.

Introduction
Onium salts are a special type of water soluble
plant growth regulators (PGRs) which are widely
used in agronomic crops. Thus, 2-chloroethyltrimethyl-
ammonium chloride (chlormequat chloride) and
1,1-dimethylpiperidinium chloride (mepiquat chloride) are
known to reduce stem elongation in crops due to a reduction
in the synthesis of gibberellic acid [1]. The use of these
PGRs significantly mproves crop production even under
environmental stresses.
Nowadays, the onium salts, also called “ionic liquids”
(ILs) are considered promising biologically active
compounds for the development of new

phytopharmaceuticals. The “tunability” of ILs in the design
of physicochemical properties and biological activity by
modification of cation or anion structure creates enormous
potential for their industrial use [2]. Thus, commercially
available phenoxy herbicides having an acidic nature have
been incorporated into ILs structure to develop a new group
of compounds defined as herbicidal ILs [2, 3]. The
combination of the herbicidal activity of the anion with
different biological activity of the cation leads to dual-
functions compounds with improved physicochemical
properties, as well as antifungal activity against plant
pathogens [3, 4].
At the same time, there is little data in the literature
regarding the plant growth-promoting activity of common
ILs comprising halogen anions. The biological activity of
these compounds is greatly affected by the length of the
aliphatic chain near the cation. From this point of view,
long-chain ILs comprising heterocyclic cations seem
especially attractive for plant protection since they combine
good water solubility, high surface activity, and a broad
range of antimicrobial activity [5].
However, the high ecotoxicity, as well as poor

biodegradability of common ILs is a serious drawback
limiting their practical applications [6, 7]. The introduction
of polar functional groups such as hydroxyl, carboxyl, or
ester into the hydrocarbon chains of ILs is an efficient
approach to reducing their toxicity [6, 8].
In this work, long-chain pyridinium salt, 1-(2-
(dodecyloxy)-2-oxoethyl)pyridin-1-ium chloride (1b) was
synthesized (see Scheme 1), and evaluated for growth-
promoting activity toward wheat seeds. Recent studies have
shown that this ester-functionalized pyridinium salt has
significantly reduced acute toxicity, as well as improved
biodegradability compared to non-functionalized analogs
[8]. At the same time, pyridinium chloride 1b was found to
have moderate antibacterial activity and high antifungal
activity that makes it a promising plant protection product.

ium chloride (1b).
Results and Discussion
The growth parameters of wheat seedlings after their
treatment with water solutions of 1-(2-(dodecyloxy)-2-
oxoethyl)pyridin-1-ium chloride (1b) are summarized in
Table 1. Pyridinium salt increased germination in the
concentration range of 0.001-0.1%. However, at the highest
examined concentration of 0.1% significant reduction in
shoot and root length was observed. It is worth noting that a
similar adverse effect on wheat seedlings growth has been
reported for short-chain imidazolium salts [9]. At lower
concentrations, pyridinium chloride 1b has a positive effect
on wheat growth parameters (Figure 1, Table 1). Thus, the
maximum increase of shoot length (by 15%) and root length
(by 7%) was determined for a substance concentration of
0.001%. Moreover, shoot and root dry mass increased by
18.3 and 24.6 %, respectively (Table 2). The hydration of
seedlings changed slightly, which indicates the absence of
any significant impact of the selected concentrations on this
physiological indicator.
The results of the analysis of pigments content in wheat
seedlings are shown in Table 3. The treatment of wheat
seeds with 1-(2-(dodecyloxy)-2-oxoethyl)pyridin-1-ium
chloride (1b) in a concentration of 0.01% increased the
content of chlorophylls and carotenoids by 25% (Ca), 20%
(Cb) and 43% (Ccar). This indicates positive effect of
pyridinium salt on photosynthetic system of plants. At the
highest examined concentration of the compound (0.1%) a
significant decrease in pigment content was determined
(Table 3). The ratio of chlorophylls to carotenoids increased
by 100% for plants treated with pyridinium chloride 1b at a
concentration of 0.1%. For lower concentrations of 0.01 and
0.001%, the (Ca+Cb)/Ccar value was similar to control
samples that indicates the absence of physiological stress in
plants.
Figure 1. 7-Days-old wheat seedlings after exposure to deionized
water (1, control) and water solutions of 1-(2-(dodecyloxy)-2-
oxoethyl)pyridin-1-ium chloride (1b) with concentrations of
0.01% (2) and 0.001% (3).

As one can see from Table 3, the main flavonoid content
was in green part of plants. Antioxidant flavonoids are
known to effectively control key stages of cell growth and
differentiation, regulating the development of the entire
plant and individual organs [10]. The content of flavonoids
in shoots grown after treatment with pyridinium salt at a
concentration of 0.1% was comparable to control samples.
For wheat seedlings treated with lower concentrations of
0.01 and 0.001% the Cfl value increased by 60 and 40%,
respectively. The last fact may indicate activating the plant
defense system under mild stress conditions [10]. Overall,
the obtained results clearly indicate that pyridinium salt 1b
has pronounced growth-promoting effect on wheat seeds in
the concentration range 0.001-0.01%. Similar results on the
effect of the polymeric biocide polyhexamethylene
guanidine hydrochloride on the morpho-physiological
parameters of wheat seedlings have also been reported [11,
12].
At the same time, imidazolium-based ILs with alkyl
chain length from 2 to 8 carbon atoms were found to reduce
the germination and growth of wheat seeds even at low
concentrations [9, 13]. Based on these results one can
assume that both the nature of the cation and the structure
of the alkyl chain are important factors determining the
biological activity of onium salts toward plants. Thus,
further studies of the effect of ester-functionalized
pyridinium salts with different alkyl substituents on the
morpho-physiological parameters of wheat seedlings are
underway.

Conclusions
In this work, a long-chain pyridinium salt 1b comprising
polar ester group in the alkyl chain has been synthesized.
The influence of the synthesized cationic surfactant on the
morpho-physiological parameters of wheat seedlings has
been studied. At a concentration of 0.1% the substance has
inhibitory effect on plant growth. However, treating seeds
with lower concentrations of pyridinium salt 1b (especially
0.001%) significantly increased growth parameters. In
particular, the growth-promoting effect of 1b was manifest-
ted in an increased seed germination, shoot and root length,
as well as dry mass in 7-day-old seedlings. Moreover, the
substance has a positive effect on the photosynthetic
characteristics of plant leaves, increasing the synthesis of
chlorophylls and carotenoids. At the same time, the ratio
between chlorophylls and carotenoids remained close to
control values, which indicates stability of the primary
photochemical processes of photosystem II.
Overall, the results of this research revealed pronounced
positive effect of ester-functionalized cationic surfactant 1b
on wheat seeds growth. The combination of antifungal
activity of this compound with high biodegradability and
growth-promoting activity toward plants makes it very
promising for various agrochemical applications. Thus,
further study of the biological activity of pyridinium salts
with different structures of the alkyl radical is of significant
interest.
Experimental section
General
Following chemicals were used for the synthesis:
pyridine (99%), chloroacetyl chloride (98%), 1-dodecanol
(99%), benzene (99.8%), ethyl acetate (98%), potassium
carbonate (99%). All chemicals were purchased from
Sigma-Aldrich and used without further purification.
Proton nuclear magnetic resonance (1H NMR)
spectroscopy was used to confirm the structure of the
synthesized compounds. Spectra were recorded in CDCl3 on
a Varian Gemini-2000 (400 MHz) NMR spectrometer using
tetramethyl silane as internal standard.
Synthesis of dodecyl chloroacetate (1a)
To the stirred mixture of 1-dodecanol (18.6 g, 0.1 mol)
and potassium carbonate (13.8 g, 0.1 mol) in 100 ml of
benzene was added chloroacetyl chloride (13.5 g, 0.12 mol)
dropwise. The reaction was carried out for 6 h at room
temperature. Then the solution was washed successively
with water until a neutral pH was achieved. Then it was
dried over calcium chloride overnight. The solvent was
removed via distillation at normal pressure. The obtained
oily product was additionally dried in vacuum 10 mbar at
60 ºC. 1H NMR (400 MHz, CDCl3) δ 4.18 (t, J = 6.8 Hz,

Biological activity
Seeds of wheat (Triticum aestivum L., cultivar
“Podolyanka”, Ukraine) were germinated by hydroponic
method in glass Petri dishes (Ø10 см) in deionized water
(control) or in water solutions of of 1-(2-(dodecyloxy)-2-
oxoethyl)pyridin-1-ium chloride (1b) with concentrations of
0.001 and 0.01%. In each Petri dish 20 seeds were sown, in
two replications. The experiment was repeated three times.
Germination was conducted in the dark at 25 ± 2 ºC.
Number of germinated seeds was counted after 24 h.
Germinated seeds were grown in a light box at 25 ± 2 ºC
under 16/8 h (light/dark) photoperiod provided by cool-
white fluorescent lamps (Philips TL-D 18W/54 T8 G13).
Primary root length (L) and shoot length (l) was
measured on 7-day-old-seedlings.
Pigments and flavonoids were extracted from 0.1 g of
dry mass (crushed and sieved through the sieve with pore
size of 1.5 mm) with 1 ml of 70% ethanol for 24 hours at
24 ºC. Total chlorophyll (Ca and Cb) and carotenoids (Ccar)
content was determined using a FLUOstar®Omega
spectrophotometer (Germany) by measuring the absorbance
of the ethanol extract of pigments at 649 and 665 nm (for
chlorophylls) and at 479 nm (for carotenoids) [14]. Total
flavonoid content of the plant extracts (Cfl) was determined
using the aluminum chloride colorimetric assay at 415 nm
[15]. Rutin was used as a reference compound.
The statistical processing and analysis of the
experimental data were conducted in Excel application of
the standard Microsoft Office XP package (Microsoft,
USA). If the samplings were subject to the normal
distribution law, Student’s T-test was used for their
comparison. The obtained results were considered reliable
at the significance level, set at p<0.05.

Резюме: Синтезовано довголанцюгову піридинієву сіль 1-(2-(додецилокси)-2-оксоетил)піридин-1-ій хлорид (1b), що функціоналізована
полярною естерною групою у складі алкільного радикала. Досліджено вплив цієї сполуки на морфо-фізіологічні характеристики проростків
насіння пшениці (схожість, довжина пагона і кореня, біомаса, вміст пігментів і флавоноїдів). Після обробки насінин водними розчинами
піридинієвої солі 1b з концентраціями 0.001-0.1% зростала їх схожість. Однак концентрація сполуки 0.1% має негативний вплив на ріст рослин і
спричиняє зменшення ростових параметрів пагонів і коренів, маси і вмісту пігментів. В той же час, обробка насінин розчинами піридинієвої солі
з меншими концентраціями (зокрема, 0.001%) сприяла зростанню довжини пагонів і коренів, а також зеленої біомаси у семиденних проростках
пшениці. За концентрації 0.01% сполука спричиняє значне збільшення вмісту хлорофілів і каротиноїдів, що свідчить про її позитивний вплив на
фотосинтетичний апарат рослин. Суттєве зростання вмісту флавоноїдів в зеленій частині рослин може свідчити про активацію захисної системи
за умов помірного стресу. Ріст-стимулюючий вплив довголанцюгової піридинієвої солі 1b на насіння пшениці у поєднанні з широким спектром
антимікробної активності та біодеструктивності сполуки свідчать про її перспективність для застосувань в агрохімічному секторі.
Ключові слова: довголанцюгова піридинієва сіль; насіння пшениці; ріст-стимулюючий ефект; захист рослин.

The influence of the substance on morpho-physiological traits of wheat seedlings (germination, shoot and root length and biomass, chlorophylls and carotenoids content, as well as flavonoid content) has been studied. The germination of seeds increased after their exposure to water solutions of pyridinium chloride 1b in the concentration range 0.001-0.1%. However, the concentration 0.1% has a negative effect on plant growth leading to reduced growth parameters in shoots and roots, plant mass, as well as pigments content. The exposure of wheat seeds to water solutions of pyridinium salt with lower concentrations (especially at 0.001%) significantly increased shoot and root length, as well as wet green mass in 7-day-old seedlings. At a concentration of 0.01%, the substance caused a significant increase of chlorophyll a, chlorophyll b, and carotenoids content thus revealing a positive effect on the photosynthetic apparatus of plant leaves. The flavonoid content in a green part of the plants also significantly increased which may indicate activating the plant defense system under mild stress conditions. The high growth-promoting effect of long-chain pyridinium chloride 1b on wheat plants, together with its broad range of antimicrobial activity and biodegradability, makes it an attractive product for various agrochemical applications Синтезовано довголанцюгову піридинієву сіль 1-(2-(додецилокси)-2-оксоетил)піридин-1-ій хлорид (1b), що функціоналізована полярною естерною групою у складі алкільного радикала.
