5 / Title of the topic / “SYNTHESIS, CHARACTERIZATION , ANTIMICROBIAL AND ANTI-DIABETIC ACTIVITY OF FEW THIOSEMICARBAZIDES DERIVED FROM ACETYL COUMARIN”
6 / BRIEF RESUME OF THE INTENDED WORK
6.1 Need ForThe Study :
Coumarins not only occur in nature but also posses very good physiological activities. It had been known since 1921. Link and coworker found that cattle feeding on spoiled sweet hay suffered from a condition characterized by sharp in crease of blood clotting time. The pathogenic hemorrhagic principle of sweet clover hay was found by them to be 3, 31-methylenebis– (4-hydroxy coumarin) popularly called Dicoumarol. It was synthesized by reacting4-hydroxy coumarin with formaldehyde and found to be a good anticoagulant of blood. Since this discovery and also because of its high reactivity, the chemistry of 4-hydroxy coumarin has assumed great importance1-2.
The compounds containing thione (>C=S) and thiol (>C-SH) groups occupy an important position among organic reagents as they posses many applications in industry, in medicine and analytical chemistry.
Thiosemicarbazides and thiosemicabazones possess good cheating properties and diversified biological activities against virus,protozoa, small pox, certain kinds of Tumors and bacteria. Considering all the above facts. It was thought that if sulfonamides group could be introduced to thiosemicarbazones moiety, the resulting compound might have some significant biological properties3.
Various hydrazines derivatives and semi-carbazides have been known to inhibit monoamine oxidase activity. Monoamine oxidase inhibitors had also been reported to exhibit marked Anti-convulsant activity4.
Various methods for synthesis of coumarins and thiocoumarines, coumarinoacetyl pyrazoles have shown moderative good activities against all fungi and bacteria5-9 .
Chromen-2-one derivatives posses diverse Biological properties such as Anti bacterial , Anti-fungal , Anti-neoplastic , Anti-tubercular , Anthalmentic , Neuroleptic , Anti-HIV , recently chromen-2-ones were reported to posses selective dopamine D4 antagonist activities10.
Some new Thiozolidines and Azolidinones of 6-amino Coumarins , 7,8-dihydroxy-4-methyl coumarins , 4-hydroxy coumarin posses Anti-bacterial , physiological , Anti-cougalant , Spasmolytic , Bacteriostatic ,Anti-toumer activity11-13.
Hence there is a need for Synthesis of compounds containing Coumarin ring and Thione group in hope of getting compound with better Biological and Pharmacological Activities.
As a part of our studies concerning, the Synthesis of Coumarin based fused heterocyclic compounds, we are interested in preparationof coumarin based fused substituted thio-semicarbazide derivatives.
6.2 Review of literature:
An extensive survcy of literature to be done by referring chemical abstracts, various international research journals in our college libraries, libraries of kuvempu university shimoga, Karnataka university Dharwad, Mysore University Mysore and Bangalore University Bangalore, Gulbarga University Gulbarga. The literature survey will also be made by visiting the various websites through internet and also by availing CD-ROM facilities I.I.S.C Bangalore.
6.3 Objectives of study:
The main objective of the present work is to synthesize the compounds containing coumarin ring and thione group in hope of getting potent biological and pharmacological compounds.In present work for the synthesis of titled compounds; acetyl coumarin
will be treated with various substituted thiosemicarbazides. The structures of the compounds will be conformed by spectroscopic data and will be screened for various biological and pharmacological activities.
7 / MATERIALS AND METHODS:
The necessary data will be generated by laboratory experimentation technique this includes,
a)Synthesis of target molecules.
b)Spectroscopic data of new compounds for structural confirmation (I.R.,NMR and Mass spectra etc.)
c)Biological and pharmacological screening and the results of activities.
7.1 Source of data:
Various national and international journals.
Chemical Abstracts.
Standard text books for carrying out screening of pharmacological activities.
Indian pharmacopoeia.
7.2 Methods of collect of data:
(Including sampling procedure if any)
a)Synthetic methodology :
Synthetic strategy for target molecules involves following procedure:
The reaction of salicylaldehyde with ethylacetoacetate in presence of piperidine give yellow solid mass of Acetyl-Coumarin14-15 which was fused with substituted thiosemicarbazide in ethanol medium to afford the corresponding Acetyl coumarin thio semicarbazide derivatives.
Reaction will be monitored by T.L.C. and products purified by recrystallisation.
b)Spectroscopic data:
IR of all new compounds will be obtained by using spectrophotometers available in our college, NMR and mass spectroscopic data will obtained from I.I.Sc. Bangalore and I.I.T. Madras etc.
c)Pharmacological and Biological Screening:
Antimicrobial activity16-17: All the synthesized compounds will be evaluated for Anti-microbial activity by cup plate method.
Anti-diabetic activity18-21: Selected compounds will be subjected to screen for Anti-diabetic activity will be carried out by alloxan induced diabetic rat.
7.3 Does the study require any investigation (or) interventions to be conducted on patients (or) other humans (or) animals? If so please describe briefly:
Investigation of Anti-microbial activity and Anti-diabetic activity requires albino rats (Wistar strain, either sex 150-200g), Analgesic activity requires mice (Swiss strain either sex 20-25g) which will be sacrificed.
7.4Has ethical clearance been obtained from your institution in case of 7.3.
Ethical clearance is available, Reg.No.157/1999CPCSEA.
