c-132

Furothiazole is a bioactive chemical.

Antibacterial agent 132 showed antimicrobial activity against C. parapsilosis (ATCC 22019) and C. krusei (ATCC 6258) with MIC90 values of <0.06 μg/mL and 62.50 μg/mL, respectively. Antibacterial agent 132 inhibited aromatase enzyme with IC50 of 0.047 μM.

Bovine Myeloid Antimicrobial Peptide (BMAP) 28, a synthetic peptide derived from bovine cathelicidin-5 (amino acids 132-158), exhibits antimicrobial activity against E. coli, S. aureus, MRSA, S. epidermidis, and the fungus C. albicans, with minimum inhibitory concentrations (MICs) of 2, 2, 4, 1, and 8 µM respectively. At a concentration of 200 nM, BMAP 28 permeabilizes the inner membrane of E. coli, and at 5 µM, it inhibits herpes simplex virus 1 (HSV-1) replication in Vero 76 cells. Furthermore, at 30 µM, it causes hemolysis in human erythrocytes and cytotoxicity in human neutrophils. In vivo, a dose of 0.8 mg/kg enhances survival in mice infected with E. coli or MRSA, but not P. aeruginosa.

Sporogen-AO 1 is a fungal metabolite originally isolated fromA. oryzaethat has diverse biological activities.1,2,3,4,5It inhibits HIV-1 Tat transactivation in a cell-based assay with an IC50value of 15.8 μM.4Sporogen-AO 1 is cytotoxic to HeLa, KB, and NCI H187 cancer cells (IC50s = 8.3, 9, and 5.1 μM, respectively).2,5It is active againstC. albicans(MIC = 4 mM).3 1.Tanaka, S., Wada, K., Marumo, S., et al.Structure of sporogen-ao 1, a sporogenic substance of Aspergillus oryzaeTetrahedron Lett.25(51)5907-5910(1984) 2.Motohashi, K., Hashimoto, J., Inaba, S., et al.New sesquiterpenes, JBIR-27 and -28, isolated from a tunicate-derived fungus, Penicillium sp.
