Zaprinast (M&B 22948) is a selective inhibitor of cGMP-selective Phosphodiesterase (PDE5). Zaprinast causes a significant increase in cGMP levels in myocytes. Zaprinast is a G protein-coupled receptor 35 (GPR35) agonist which activates rat GPR35 strongly and activates human GPR35 moderately. Zaprinast reduces vessel remodeling through antiproliferative and proapoptotic effects.

3-Epiursolic Acid is a triterpenoid that can be isolated from Eriobotrya japonica, acts as a competitive inhibitor of cathepsin L (IC50, 6.5 μM; Ki, 19.5 μM), with no obvious effect on cathepsin B.

Veliparib dihydrochloride is an orally active and potent inhibitor of both PARP-1 and PARP-2 with Kis of 5.2 nM and 2.9 nM, respectively. It exhibit ability to cross the blood-brain barrier and potentiate DNA-damaging agents in preclinical tumor model.

2′-Deoxy-2′-fluorocytidine, an nucleoside analog, is a potent inhibitor of Crimean-Congo hemorrhagic fever virus (CCHFV) replication. 2′-deoxy-2′-fluorocytidine can act synergistically with T705 to increase the potency of both compounds antiviral effects on CCHFV replication.

Virginiamycin M1 (Pristinamycin IIA; Ostreogrycin A), produced by Streptomyces virginiae, is an polyunsaturated macrocyclic lactone antibiotic and acts as a component of Virginiamycin (HY-112665). Virginiamycin M1 alone is against Staphylococcus aureus with a MIC of 0.25 μg/mL.

(±)-Huperzine A, an active Lycopodium alkaloid extracted from traditional Chinese herb, is a potent, selective and reversible acetylcholinesterase (AChE) inhibitor and has been widely used in China for the treatment of Alzheimer’s disease (AD).

Canthaxanthin is a red-orange carotenoid with various biological activities, such as antioxidant, antitumor properties.

A-674563 is a selective, orally active inhibitor of Akt1 with a Ki of 11 nM. It also inhibits PKA with Ki of 16 nM and CDK2 with Ki of 46 nM. A-674563 reduces Akt downstream target phosphorylation and inhibits tumor cell proliferation in vitro with an EC50 of 0.4 µM.

Zearalenone is a nonsteroidal estrogenic mycotoxin produced by Fusarium species, which colonizes several grains. Zearalenone has low acute toxicity and carcinogenicity. Due to its agonistic effect on the estrogen receptor, Zearalenone exhibits distinct estrogenic and anabolic properties in several animal species, resulting in severe effects on the reproductive system.

Bremelanotide (PT-141) is an analogue of α-melanocyte-stimulating hormone (α-MSH). Bremelanotide activates the mPOA and other hypothalamic and limbic regions of the brain involved in sexual behavior. Bremelanotide can be used for researching hypoactive sexual desire disorders.
