1, 5-Benzo Thiazepine is the Main Seven membered Heterocyclic ring systems reported for their cardiac and Psychotherapeutic activities.1,5 Benzo Thiazepines were highlighted as important Biologically active Scaffolds. In This Article New series of benzo [b] [1, 5]-thiazepine derivatives 6 a-j were synthesized by applying the cyclo condensation of (E)-3-(thieno [3, 2-d] pyrimidin-6-yl)-1-p-Substituted prop-2-en-1-one derivatives 4a-j with 2-amino thio phenol (5) in DMF. The new intermediate Chalcone derivatives 4a-j were obtained from interaction of various P-substituted Acetophenone&Heterocyclic Acetyl derivatives 3(a-j) and thieno[3,2-d]pyrimidine-7-carbaldehyde. The synthesized 1, 5-benzothiazepines 6a-j have been screened for their antimicrobial activity. From anti-bacterial and anti-fungal activity screening results, it has been observed that compounds 6h, 6e, 6i and 6d possess good activity.Keywords
Chalcones, 2-Amino Thio Phenol, Cyclisation, 1, 5-Benzothiazepines, Anti-Microbial Activity, Thieno [3, 2-d] Pyrimidine Core Ring.

Quinazoline nucleus is present in various compounds and it is responsible for diverse biological activities. The present work mainly focused on the Quinazolines with potential activities that are now in development. The objective of this research work is to synthesize various compounds containing Quinazoline moiety and their derivatives as well as characterising the compounds by spectral analysis and screening for antimicrobial and anticancer activities. The structures of synthesized compounds were confirmed by various spectroscopic methods such as IR, NMR and mass spectroscopy. The products were evaluated for their antimicrobial activity against several microbes. Some of the compounds exhibited potent anti-bacterial activity as well as anti-fungal activity. Among the Novel Quinazoline derivatives 8i, 8j, 8d shows Excellent Anti-microbial activity.Keywords

A series of novel 4-Substituted/Heterocyclic-N-(4-thiomorpholinothieno[3,2-d]pyrimidin-2-yl)benzamide (8a-j) derivatives were synthesized by a Five-step procedure that afforded advantages of mild reaction conditions, simple protocol and good yields. The structures of the final compounds were confirmed by IR, NMR, EI-MS. The final compounds were screened for their anti-bacterial activity against Staphylococcus aureus (S. aureus) and Bacillus subtilis (B. subtilis)from Gram positive group of bacteria and Pseudomonas aeruginosa (P. aeruginosa) and Escherichia coli (E. coli) from Gram negative group of bacteria and antifungal activity against Aspergillus niger (A. niger) and Candida albicans (C. albicans). Anti-bacterial and anti-fungal activities were Evaluated and compared with the standard drugsSuch asAmoxicillin &Flucanazole From anti-bacterial and antifungal activity screening results, it has been observed that compounds 8j, 8i, 8e and 8f possess good activity.Keywords
