Triacsin C
Based on 9 publication(s) in Google Scholar
Triacsin C (WS 1228A), is an orally active and intracellular long-chain acyl-CoA synthetases (ACSL) inhibitor, which can be isolated from Streptomyces aureofaciens. Triacsin C inhibits TAG accumulation into lipid droplets (LD) by suppressing ACSL activity. Triacsin C exhibits highly inhibitory effect against rotavirus replication.

Triacsin C (0-16 μM; 41 h) inhibits parasite fatty acyl-coenzyme A synthetases, and reduces CpACS1 and CpACS2 enzymes activities with IC50s of 3.70 μM and 2.32 μM, respectively, with Ki values of 595 nM and 106 nM, respectively[3].
Triacsin C (0-16 μM; 41 h) shows anti-parasitic and inhibits Cryptosporidium parvum with an IC50 value of 136 nM[3].
Triacsin C (0, 0.25, 0.5 μM; 30 min) has no effect on parasite invasion[3].
