3-Hydroxyterphenyllin

3-Hydroxyterphenyllin is a p-terphenyl fungal metabolite originally isolated from A. candidus that has diverse biological activities, including antioxidant, antiproliferative, antibacterial, and antiviral properties.{42907,42908,38480,37200} It has a 96% scavenging effect on 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH; Item No. 14805) when used at a concentration of 100 ?g/ml.{42908} 3-Hydroxyterphenyllin inhibits the growth of HeLa cervical, A549 lung, and HepG2 liver cancer cells (IC50s = 23, 36, and 32 ?M, respectively), as well as methicillin-resistant S. aureus (MRSA) and V. vulnificus bacteria (MIC = 31 ?g/ml for both).{38480} It also inhibits HIV-1 integrase in both coupled and strand transfer assays (IC50s = 2.8 and 12.1 ?M, respectively).{37200}
