Vinaxanthone (SM-345431) is a small molecule compound derived from Penicillium chrysogenum that acts as a selective and potent inhibitor of semaphorin3A, phospholipase C (PLC), and FabI, exhibiting antimicrobial activity by blocking intracellular fatty acid synthesis and inhibiting the growth of Staphylococcus aureus.

Sinapinic Acid (Synapoic acid) protects the rat liver from CCl4-induced inflammation, most likely by acting as a free radical scavenger and modulator of NF-κB p65 activation and proinflammatory cytokine expression. Sinapic acid with antioxidant role protects cardiac cells and its functions from I/R induced oxidative stress. Sinapic acid is a potentially useful agent for the protection against liver fibrosis and cirrhosis. Sinapic acid prevents the alterations in the levels of lipids and lipoproteins by virtue of its anti-lipidaemic effect in isoproterenol induced myocardial infarcted rats. Sinapic acid ameliorates hyperglycemia through PLC-PKC signals to enhance the glucose utilization in diabetic rats.

Phosphatidylinositol 4,5-bisphosphate (L-alpha-Phosphatidylinositol-4,5-bisphosphate), a critical phospholipid in cell membranes, serves as a substrate for both phospholipase C (PLC) and phosphoinositide 3-kinase (PI3K) and acts as a primary messenger [1] [2] [3].

Plipastatin A1, a lipopeptide isolated from B. cereus, demonstrates enzyme inhibitory and immunosuppressant properties. It effectively inhibits enzymes phospholipase A2 (PLA2), phospholipase C (PLC), and phospholipase D (PLD) with half-maximal inhibitory concentrations (IC50s) of 2.9, 1.3, and 1.4 µM, respectively. Additionally, at a concentration of 100 µg/ml, plipastatin A1 inhibits lipopolysaccharide (LPS)-induced B cell blastogenesis and T cell blastogenesis triggered by concanavalin A. In vivo studies reveal that a dose of 0.1 mg/animal effectively suppresses delayed-type hypersensitivity in mice.

2α,3α,24-Trihydroxyurs-12-en-28-oic acid, a triterpenoid phytoalexin, shows antifungal activity against the fungus mentioned. It also shows in vitro cytotoxic activity against tumor cell lines including PLC,Hep3B,HepG2,HeLa,SW480,MCF-7 and Bel7402.

Asterriquinone (ARQ) is an analog of Asterriquinone and a Grb-2 binding inhibitor. It hinders the interaction between Grb-2 and tyrosine-phosphorylated EGFR, with an IC50 of 8.37 μM. Additionally, Asterriquinone serves as an HIV1 reverse transcriptase inhibitor, with a Ki of 2.3 μM, and it also inhibits the binding activities of Grb-7 and PLC-γ.
