Di azepines, which were synthesized by different methods shown in literature and also Di azepines are great importance in heterocyclic chemistry and more importance in biology and pharmacology. Di azepines are very biological active molecules. In this work A new series of 1, 5-Benzodizepine derivatives were synthesized from chalcones and evaluated for their Antimicrobial activities. First Chalcones were prepared by treatment of Thieno [2, 3-d] pyrimidine-6-carbaldehyde with different acetophenones by Claisen-Schimidt Condensation. Various Benzodiazepines derivatives were prepared by reaction of Chalcone in DMF with o-phenylene di amine in presence of piperidine. The structures of the newly synthesized Benzodiazepine derivatives have been established on the basis of their spectral data. The synthesized selected compounds were evaluated for their antimicrobial activities.

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.

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

A Novel Series of Compounds were synthesized by Condensation reaction of Carbazole aldehyde with Substituted Acetophenone derivatives 4 (a-d) in presence of alcoholic Sodium hydroxide Solution to get Chalcone Intermediates 5 (a-d), which were further treated hydroxyl amine hydrochloride in presence of Pyridine to get Iso Oxazoline Derivatives 6 (a-d). The latter were refluxed with Substituted Primary amines and formaldehyde for 8–10 hrs to get Mannich bases. The Structures of new compounds were confirmed by IR and 1H NMR and 13C NMR Spectral Data. Anti-bacterial and Anti-fungal Activities were evaluated and compared with the standard drugs, some compounds of the series Exhibited Promising Anti-microbial and Anti-fungal Activity Compared to Standard Drugs.
