6. BRIEF RESUME OF THE INTENDED WORK.

6.1 Need for the study.

The chemical and biological potentials of five-membered heterocyclic compounds fused with aromatic nuclei have attracted the attention of organic and medicinal chemists for several years. Most of the research programme efforts are directed towards the design of new drugs, because of the unsatisfactory status of present drug side effects and the resistance by the infecting organisms to present drugs.

Sulphur containing heterocycles are the active research in the pharmaceutical chemistry. Now a days benzothiophene derivative in combination with other ring systems have been used extensively in pharmaceutical applications such as antiallergic, analgesic, anti-inflammatory etc.

The present study is focused on the development of new potent heterocyclic moieties containing benzothiophene nucleus for enhancing better biological and pharmacological properties.

6.3 Objective of the Study

In view of the significance of naturally occurring and physiologically active benzothiophene stimulated our interest in the synthesis of several heterocyclic compounds containing benzothiophene ring either in fused form or as substituted.

The newly synthesized molecules will be established on the basis of physical data, analytical data and spectral studies such as IR, 1H NMR, 13C NMR and mass and were screened for their biological and pharmacological activities on the basis of literature survey. The results of biological and pharmacological activities of the newly synthesized compounds were compared with standard drug.

ENCLOSURE- IV

6.4 METHODOLOGY

In the present investigation required starting material substituted benzo(b)thiophenes was prepared when substituted cinnamic acid was made react with thionyl chloride under reflux condition. Then the intermediate was converted into different heterocyclic compounds.

All the synthesized compounds will be evaluated for invitro antibacterial activity.

ENCLOSURE- V

7. MATERIALS AND METHODS

7.1 Source of data

In the present investigation we planned to synthesized benzothiophene derivatives by closing the thiophene ring on the benzoid ring. This synthetic work mainly a laboratory based work. All the basic facilities which required carrying out are available in our laboratory.

The literature survey pertaining to present investigation will done by referring chemical abstracts, internet, national and international journals.

The day to day development in the area will be updated by literature survey through e-publishing, internet and current periodicals in our library and else where.

ENCLOSURE- VI

7.2 Method of collection of data.

The chemical structure of synthesized compounds will be established on the basis of physical, chemical and analytical data. Melting point of newly synthesized compounds will be determined by open capillary tube and is uncorrected they are expressed in degree centigrade. The compounds synthesized will be characterized by IR, 1HNMR and Mass Spectral data. This will be collected by sending the sample to other advanced research center.

The main objective of the present investigation is to explore newer molecule with potent biological and pharmacological activities.

7.3  Does the study require any investigation or investigations to be conducted on patients or other human or animals? If so, please describe briefly.

Yes, at the later stage, after successful synthesis of molecules. The compound will be screened for pharmacological actions on albino mice and rats.

7.4 Has ethical clearance been obtained from your institution in case?

Yes ethical clearance committee had been obtained by our Institution.
