Benanomicin A is a microbial metabolite that has been found inActinomycetesand has antifungal, fungicidal, and antiviral activities.1,2It is active against a variety of mammalian and plant pathogenic fungi, includingC. albicans,T. mentagrophytes,C. neoformans,P. oryzae, andA. niger(MICs = 3.13-50 μg/ml).1Benanomicin A inhibits HIV-1 viral infection in MT-4 cells in a concentration-dependent manner.2 1.Takeuchi, T., Hara, T., Naganawa, H., et al.New antifungal antibiotics, benanomicins A and B from an actinomyceteJ.

9(S),12(S),13(S)-TriHOME is a linoleic acid-derived oxylipin that has diverse biological activities.1,2,3,4It has been found in various plants and is produced in human eosinophils in a 15-lipoxygenase-dependent, soluble epoxide hydrolase-independent manner.1,59(S),12(S)13(S)-TriHOME inhibits antigen-induced β-hexosaminidase release from RBL-2H3 mast cells (IC50= 28.7 μg/ml).2It inhibits LPS-induced nitric oxide (NO) production in BV-2 microglia (IC50= 40.95 μM).3In vivo, 9(S),12(S),13(S)-TriHOME (1 g/animal) enhances the antiviral IgA and IgG antibody responses induced by a nasal influenza hemagglutinin (HA) vaccine by 5.2- and 2-fold, respectively, in mice.4 1.Hamberg, M., and Hamberg, G.Peroxygenase-catalyzed fatty acid epoxidation in cereal seeds: Sequential oxidation of linoleic acid into 9(S),12(S),13(S)-trihydroxy-10(E)-octadecenoic acidPlant Physiol.110(3)807-815(1996) 2.Hong, S.S., and Oh, J.S.Inhibitors of antigen-induced degranulation of RBL-2H3 cells isolated from wheat branJ.
