5-Methyl-3,8-di-(2-amino-4-bromophenyl)-4,9-dioxa-1,2,6,7-tetraaza-5λ5-phosphaspiro[4.4]nona-2,7-diene – Synthesis and Preliminary Cytotoxic Screning

5-Methyl-3,8-di-(2-amino-4-bromophenyl)-4,9-dioxa-1,2,6,7-tetraaza-5λ5-phosphaspiro[4.4]nona-2,7-diene was obtained in a condensation reaction of 2-amino-5-bromobenzohydrazide and methylphosphonyl dichloride in the presence of triethylamine. An initial biological screening was performed for the obtained product. The synthesized compound possesses two aromatic primary amine groups and two bromine atoms within the structure, which are suitable for further structural modifications.

Synthesis, Characterization and Antimicrobial Activities of some Novel 3-(4-Bromobenzyl)-5-(Thiophen-2-yl)-4H-1,2,4-Triazol Derivatives

A convenient and promising synthesis of 4-(alkyl/aryl)- 3-(4-bromobenzyl)-5-(thiophen-2-yl)-4H-1,2,4-triazol was carried out by the reaction of 2-(4-bromobenzyl)-5-(thiophen-2-yl)-1,3,4-oxadiazole with different aliphatic/aromatic primary amine without any solvent. The newly synthesized compound were characterized by1H NMR, IR and Mass spectroscopy and also screened for their antimicrobial activity against various strains of bacteria and fungi.
