ABSTRACT: Hydrazones are an important classe of biologically active compounds found in many synthetic compounds. In view of their importance in synthetic chemistry, the present article reported that a new series of novel hydrazone derivatives (4a-e) were synthesized by condensation of 3-((4-formyl-2-methoxyphenoxy)methyl)benzonitrile(3) with different benzohydrazides and confirmed by their IR, 1H NMR, and Mass spectral data. Further these synthesized derivatives (4a-e) were evaluated for their biological activities such as antiinflammatory, analgesic, and antibacterial activities. All the derivatives were showing the pharmacological activities mainly due to the presence of pharmacophore, azomethine group (CONH- N=CH) and were modified with various substituents. Among all the compounds 4a, 4d, and 4e incorporated with 4-methoxy, 4-chloro and 2,4-dichloro moieties exhibited more antiinflammatory activity and the remaining compounds 4b and 4c incorporated with 4-bromo and 2-bromo substituents showed moderate activity when compared with standard reference, indomethacin. The compounds 4d, 4e and 4b showed good analgesic activity and remaining compounds 4a and 4c showed moderate activity comparable to that of standard drug diclofenac. The compounds 4a and 4e exhibited excellent antibacterial activity and the compounds 4b, 4c and 4d showed less activity when compared with standard drug, Gentamycin

INTRODUCTION: Hydrazones constitute biologically active drug molecules. Hydrazone derivatives are containing highly reactive azomethine group (CONH- N=CH) and thus useful in new drug development 1.Recently, a lot of biologically important hydrazone derivatives with a number of functional groups have been synthesized from aromatic and aliphatic compounds 2.
New compounds are being synthesized as drugs in order to combat diseases with maximal therapeutic effects and minimal toxicity. Hydrazones are used for the synthesis of novel heterocyclic compounds 3. Hydrazones have attracted a considerable attention of medicinal chemists due to their wide range of biological importance in medicinal chemistry. Many studies have confirmed that hydrazone derivatives exhibit a wide spectrum of biological activities including anti-inflammatory 4, 5 analgesic 6, 7 antibacterial 8, 9 antifungal10, 11, anticancer 12, antioxidant13, 14 antidepressant 15, antitubercular 16, cytotoxicity 17, antiamoebic 18, antitumor 19, antiplatelet 20, anticonvulsant 21, antimycobacterial 22, antihypertensive 23 and antinociceptive 24 activities. Encouraged by the biological applications of hydrazones, the present research work is aspired to describe synthesis, characterization and antiinflammatory, analgesic and antibacterial activities of novel hydrazone derivatives 4a-e derived from vanillin.

Animals and Instruments used:
Adult Wistar rats of either sex weighing between 150-200g were used for the study of anti-inflammatory activity. Adult Wistar mice of either sex (20-25 g) were used for the study of the analgesic activity. All experimental procedures were carried out according to the guidelines given by the Committee for the Purpose of Control and Supervision on Experiments on Animals (CPCSEA) and were approved by the Institutional Animal Ethics Committee with registration number. 1722/RO/ERe/S/13/CPCSEA.
All the synthesized compounds were tested for in vivo antiinflammatory activity 25 in adult wistar rats by paw edema method and edema was produced by using Carrageenan, foot volume measured by using plethysmometer. Analgesic activity 26 was carried in adult wistar mice by using Eddy's hot plate method. In vitro antibacterial activity 27 was done by the disk diffusion technique.
Pharmacological screening:
The synthesized compounds were screened for anti inflammatory, analgesic, and antimicrobial activities. The test dose for the synthesized compounds was fixed as 10 mg/kg for anti inflammatory and analgesic activities and fixed as 100 and 200 µg ̸ mL for antimicrobial activity. Indomethacin was taken as the standard drug for anti inflammatory activity and Diclofenac sodium was taken as the standard drug for analgesic activity. Gentamycin was used as standard drug for antimicrobial activity.
Anti inflammatory activity by paw edema method:
Adult Wistar rats of either sex with a body weight between 150-200g were used to study anti inflammatory activity. The animals were starved overnight. The test drug and standard were suspended in 1%CMC (control) and given orally. Thirty minutes later, 0.05 ml of 1% solution of carrageenan was given by a subcutaneous injection into the plantar side of the left hind paw of all the rats. The paw volume was measured by using plethysmometer after injection. Then the paw volume was again measured after 1h, 2h, 3h and 4h time intervals. The results were summarized in Table 1.
Analgesic activity by Eddy's hot plate:
Adult Wistar mice of either sex (20-25 g) Were weighed and numbered, the basal reaction-time was noted by observing hind paw licking in animals when placed on the hot plate maintained at constant temperature (55ºC). Drug was given by oral route to animals and noted the reaction time of animals on the hot plate at 30, 60, 90, 120 and 180 min after the drug administration. The percent increase in reaction-time (as index of analgesia) was calculated at each time interval. The results were shown in Table 2.
Antibacterial activity by disk diffusion method:
The antibacterial activity of the synthesized compounds was determined by the standard disk diffusion method. The test organism chosen were Escherichia coli and Bacillus subtillis. The concentration of the sample compounds and the standard was prepared as 100 and 200 µg ̸ mL in DMSO. Gentamycin was used as standard drug. The antimicrobial study was conducted for the determination of following parameters like, Zone of Inhibition and MIC (minimum inhibitory concentration), Different concentrations of synthetic chemical compounds were tested for anti-microbial activity by disc diffusion method. Nutrient agar medium was inoculated with different microorganisms and once the media was solidified, it was punched with a 6 mm diameter well. The tested compounds solutions were prepared in DMSO and evaluated them for their in vitro antibacterial activity against Bacillus subtillis, and Escherichia coli respectively. Agar plates containing bacteria and synthetic chemical compounds were incubated at 37ºC for 24 hrs. Antimicrobial activity was evaluated by measuring the inhibition zone. The zone of inhibition obtained by different synthesized compounds was compared with that of standard drug Gentamycin. The results were given in Table 3.
RESULTS AND DISCUSSION:
Chemistry:
The synthesized hydrazone derivatives 4a–e explained in this paper were prepared according to the synthetic Scheme 1. Vanillin 1 present in the solution mixture of K2CO3 and DMF was condensed with 3-(bromomethyl) benzonitrile (2) by stirring at 80oc, for 2h to get the pure compounds (3) in 95% yield. To the solution of 3-((4-formyl - 2 - methoxyphenoxy) methyl) benzonitrile (3) in ethanol, add Benzohydrazide derivatives (a-e) and refluxed for 1h to obtain the pure compounds 4a-e. The yield of the product varied from 89 – 97%. The structures of the synthesized hydrazone derivatives 4a-e were confirmed by IR, 1H NMR and Mass spectral data. The 1H NMR data for the derivatives 4a–e were in agreement with the assigned structures. All the aliphatic and aromatic protons were observed at expected regions. The mass spectra of compounds 4a-e showed (M+1) peaks, in agreement with their molecular formula.
Biological evaluation:
Anti-inflammatory activity:
The newly prepared hydrazone derivatives 4a-e were screened for anti-inflammatory activity at concentration 10 mg/kg by carrageenan paw edema method. Among all tested compounds, 4a, 4d and 4e exhibited maximum activity, while compounds 4b and 4c showed moderate activity when compared with standard indomethacin, anti inflammatory agent. In general, it is observed from Table 1 and that the compounds having 4-methoxy, 4-chloro, and 2, 4-dichloro exhibited excellent anti inflammatory activity and remaining compounds showed moderate activity. As all the tested compounds emerged as active against inflammation, it indicates that this basic moiety can be a promising scaffold for anti inflammatory drugs.
Analgesic activity:
The newly prepared chalcone derivatives 4a-e were screened for analgesic activity at concentration 10 mg/kg by using hot plate method. Among all tested compounds, 4d, 4e and 4b showed maximum activity, while compounds 4a and 4c showed moderate activity when comparable with disease control. In general, it is observed from Table-2 and that the compounds having 4-chloro, 2, 4-dichloro and 4-bromo, exhibited excellent analgesic activity and remaining compounds showed moderate activity. As all the tested compounds emerged as active against analgesia, it indicates that this basic moiety can be a promising nucleus for analgesic drugs. It may be suggested that this basic moiety can be a promising scaffold for analgesic drugs.
Anti- Bacterial Activity:
The anti-bacterial activity of 4a–e compounds was determined by the disc diffusion method with Gentamycin (100 & 200µg ̸ mL) as the reference standard. The synthesized compounds were screened against two Gram positive bacterial strains viz., Escherichia coli, and Bacillus subtillis. The outcome of the results are presented in the Table-3, it is evident from the results that, compounds 4a, 4d and 4e exhibited high activity against the Escherichia Coli bacteria, the rest of the compounds were found to be moderately active (4b and 4c) against the Escherichia Coli. The compound 4a exhibited high activity against the Bacillus subtilis bacteria, the rest of the compounds were found to be moderately active (4b, 4c, 4d and 4e) against the Bacillus subtilis. It is observed from the above anti-bacterial data that within the hydrazone derivatives 4a-e, compounds incorporated with the substituents such as 4-methoxy, and 2, 4-dichloro exhibited excellent antibacterial activity.
