Exeporfinium (XF-73), a dicationic porphyrin derivative, is an antibacterial drug. Exeporfinium acts via a bacterial cell-surface mechanism that affects membrane permeability and integrity, leading to release of intracellular components and bacterial cell death, without lysis. Exeporfinium represents a broad-spectrum Gram-positive antibacterial drug. It also has activity against a number of Gram-negative bacteria. Exeporfinium has been granted Fast Track designation by the US FDA for the prevention of post-surgical staphylococcal infections such as Methicillin Resistant Staphylococcus aureus.

HKI-357 is a potent, dual irreversible inhibitor of ErbB2 (HER2) and EGFR. HKI-357 suppresses ligand-induced EGFR autophosphorylation and cell proliferation in NCI-H1975 cells containing L858R and T790M mutations.

HSD-016 was discovered as an orally efficacious 11β-hydroxysteroid dehydrogenase type 1 inhibitor for the treatment of diabetes. The phase I in clinical trials for the drug was completed; however, information about further studies is not available.

INCB9471 is a non-competitive, potent and selective CCR5 small-molecule antagonist patented by pharmaceutical company Incyte Corporation for treatment of human immunodeficiency virus infection. INCB9471 potently inhibited macrophage inflammatory protein-1beta-induced monocyte migration and infection of peripheral blood mononuclear cells by a panel of R5-HIV-1 strains. INCB9471 was shown to be safe and highly efficacious in reducing HIV viral load in phase I and II human clinical trials

JTK-853, a piperazine derivative, is a non-nucleoside inhibitor of the hepatitis C virus (HCV) RNA-dependent RNA polymerase. It is under development for the treatment of hepatitis C virus infection.

IOWH032 is a synthetic extracellular CFTR inhibitor, originally developed to treat diarrhea, that entered Phase II clinical trials in 2013 but did not progress further in clinical development. iOWH032 has low CFTR inhibition potency (IC50 > 5 uM) and hence rapid (seconds or less) dissociation from CFTR. iOWH032 inhibited secretion by nearly 70% as measured on a semi-quantitative fecal output scale.

PKI-179 is an orally efficacious dual PI3K/mTOR inhibitor, possessing antineoplastic activity. The key residues involved in binding of PKI-179 were Ala-805 in PI3Kγ and Ile-2163 in mTOR as they have lost maximum accessible surface area due to binding. By inhibiting the PI3K/mTOR signaling pathway, this agent may inhibit tumor cell proliferation and survival. Evaluation of in vivo efficacy in the nude mouse model bearing MDA-361 human breast cancer tumors showed pronounced tumor growth arrest when dosed above 10 mg/Kg.

BPR0L075 [6-methoxy-3-(3',4',5'-trimethoxy-benzoyl)-1H-indole] is an anti-microtubule drug and is a promising anticancer compound with antimitotic activity. It has potential for management of various malignancies, particularly for patients with drug resistance. BPR0L075 inhibits tubulin polymerization through binding to the colchicine-binding site of tubulin.

4,4’-Diamino-2,2’-stilbenedisulfonic acid (also known as amsonic acid) is used in the synthesis of dyes and optical brighteners or fluorescent whitening agents. Amsonic acid possesses estrogenic activity, and thus provided a possible mechanistic explanation for the complaints of impotency in factory workers exposed to this compound. In the 2-year feed studies on rodents, there was no evidence of carcinogenic activity of amsonic acid, in male or female F344/N rats receiving 12,500 or 25,000 ppm. In addition, there was no evidence of carcinogenic activity of this compound in male or female B6C3F1 mice receiving 6,250 or 12,500 ppm.
