SHMT-IN-2 (compound 2) is a specific human SHMT1/2 small molecule inhibitor that acts on SHMT1 (IC50: 13 nM) and SHMT2 (IC50: 66 nM). SHMT-IN-2 inhibits the growth of many human cancer cells and is sensitive to B-cell lymphoma.

Citrinin (NSC 186) is a mycotoxin that causes food contamination and has different toxic effects. Citrinin is an effective oral anticancer agent. Citrinin has various regulatory effects on mouse immune system, including regulating the number of immune cells, inducing apoptosis and autophagy of immune cells, altering toll-like receptor expression and cytokine production. Citrinin can induce oxidative stress and lead to early apoptosis of oocytes. Low doses of Citrinin have neuroprotective effects against glutamate-induced excitotoxicity in rat cortical neurons. In addition, Citrinin also has antibacterial activity.

BPH-715 inhibits the liver-stage growth of P. falciparum with an IC50 of 10 μM for P. falciparum exoerythrocytic forms in HepG2 cells.
