Synthesis and Antibacterial Activity of Benzotriazole Substituted Acridines

Benzotriazole-Mediated Synthesis and Antibacterial Activity of Novel N-Acylcephalexins

Cephalexin (1) was acylated using N-acylbenzotriazoles (3a-k') derived from various carboxylic acids including aromatic, heterocyclic and N-Pg-α-amino acid to afford N-acylcephalexins in excellent yields (82%-96%). Antibacterial screening of the novel cephalosporins revealed that all targets (4a-j) retained the antibacterial activity of cephalexin against Staphylococcus aureus (ATCC 6538). N-Ni...

Synthesis and antibacterial activity of novel 3-substituted carbacephems.

A series of novel 3-heterocyclothio substituted carbacephems having phenylglycyl side chain have been prepared starting from 3-H carbacephem. The compounds exhibit better chemical stability than the corresponding cephalosporin and strong activity against Gram-negative and Gram-positive organisms including Enterococcus faecalis.

Synthesis and Study of Antitumor Activity of Substituted Imidazolecarboxamides

      In view of potential biological activities of small molecule polyamides, we synthesized some novel N-(2-aminoethyl)-1-benzyl-2- (alkylthio)-1H-imidazole-5-carboxamide (7a,b), and N-(2-(1-benzyl-2-(alkylthio) -1H-imidazole- 5-carboxamido) ethyl)-1-benzyl-2- (alkylthio)-1H-imidazole-5-carboxamides (8a,b) as antitumor agents. The antitumor activity of compounds 7a,b and 8a,b was studied at c...

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
