Novel oligomer metal complexes (2a–f) of the ligand 2,5-bis((4-bromophenyl)carbamoyl) terephthalic acid (1) were prepared using transition metal salts and characterized by various spectroscopic techniques. The geometry of oligomer metal complexes was carried out by electronic spectral analysis and magnetic measurement studies. Polymeric properties have also been carried out. Ligand was synthesized using pyromellitic dianhydride and 4-bromoaniline. It was duly characterized. All novel synthesized compounds 1 and 2a–f were evaluated for their antibacterial and antifungal activity. The results showed significantly higher antibacterial and antifungal activity of oligomer metal complexes compared to the ligand.

New series of fused 1,2,4-triazoles, i.e., 3-(4-isopropylphenyl)-6-substituted phenyl-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazoles (5a-5j) have been synthesized via a four-step procedure and using eco-friendly reaction condition at some steps of the synthesis. It was adopted by the formation of hydrazide of methyl 4-isopropylbenzoate (1) followed by reaction with CS2 in basic media to afford potassium salt, which on cyclized to our essential step, 4-amino-5-(4-isopropylphenyl)-4H-1,2,4-triazole-3-thiol (4). The desired adducts (5a-5j) were formed by (4) on reaction with various aromatic acids in POCl3 media. The newly synthesized triazolo- thiadiazoles have been characterized by different spectroscopic techniques and investigated for their in vitro antibacterial and antifungal activity. It was revealed that the compounds 5a, 5c, 5h, and 5i showed interesting antibacterial and antifungal activity compared to the used reference standard.

An efficient Synthesis of a novel series of N,7-bis(substitutedphenyl)-4,7-dihydro-5-isopropyl-[1,2,4]triazolo-[1,5-a]pyrimidine-6-carboxamide (4a-j) was accomplished from N-(substituedphenyl)-4-methyl-3-oxopentanamide, 3-amino-1,2,4-triazole and different aldehyde reflex 20 min with DMF and then after the cooling product was obtained. All the recently synthesized compounds were characterized by the Mass, IR, 1H-NMR and mass spectroscopic techniques and by elemental analyses. The newly synthesized compounds were assessed for their antibacterial and antifungal activity.

The synthesis and characterisation of title complexes of the ligand Methylquinolino[3,2-b][1,5]benzodiazepine (MQBD) and Methyl-quinolino[3,2-b][1,5]benzoxazepine (MQBO) are reported. The complexes have been characterized by elemental analysis, molar conductance, magnetic studies, IR,1H NMR and UV-visible studies. They have the stoichiometry [ML2Cl2] where M=Co(II)/Ni(II), L=MQBD/MQBO and [MLCl2] where M=Zn(II)/Cd(II), L=MQBD/MQBO. The antibacterial and antifungal activity of the metal complexes has been investigated.

Abstract Two new antibiotic metabolites, dacrymenone (1) and VM 3298-2 (2), were isolated from fermentations of a Dacrymyces sp., and their structures were determined by spectroscopic techniques. Dacrymenone (1) is a new eremophilane sesquiterpenoid while VM 3298-2 (2) is a bis-enol ether between methyl pyruvate and 4,6-dihydroxycyclohexan-1,3-dione. Dacrymenone (1) shows weak antibacterial and antifungal activity while VM 3298-2 (2) exhibits cytotoxic and antifungal activities.
