SKI-178 is a sphingosine kinase 1 (SphK1) inhibitor with IC50 of 0.1-1.8 μM. It induces prolonged mitosis followed by apoptotic cell death through the intrinsic apoptotic cascade. The sustained activation of CDK1 during prolonged mitosis, mediated by SKI-178 leads to the simultaneous phosphorylation of the prosurvival Bcl-2 family members, Bcl-2 and Bcl-xl, as well as the phosphorylation and subsequent degradation of Mcl-1.

NCT-502 (N-(4,6-dimethylpyridin-2-yl)-4-[5-(trifluoromethyl)pyridin-2-yl]piperazine-1-carbothioamide) is a human phosphoglycerate dehydrogenase inhibitor, cytotoxic to PHGDH-dependent cancer cells. It decreases glucose-derived serine production and it has an IC50 of 3.7 μM against PHGDH.

Daniquidone (Batracylin) is a potent dual inhibitor of DNA topoisomerase I and DNA topoisomerase II with cytotoxic and antiproliferative activity that induces DNA fragmentation for the study of neoplasms, immune disorders, and lymphatic disorders.

Triciferol acts as a multiple ligand with combined VDR agonist and HDAC antagonist activities. Triciferol binds directly to the VDR ( IC 50 =87 nM), and functions as an agonist with 1,25D-like potency on several 1,25D target genes. Triciferol induces marked tubulin hyperacetylation, and augments histone acetylation. Triciferol also exhibits efficacious antiproliferative and cytotoxic activities in cancer cell models in vitro [1].

TP-16 is a novel potent and selective EP4 antagonist that blocks the function of IMCs and enhances cytotoxic T cell-mediated tumor elimination in vivo.

Sulfosuccinimidyl oleate sodium is a long-chain fatty acid that inhibits fatty acid transport into cells and is a potent and irreversible inhibitor of the mitochondrial respiratory chain and has anti-inflammatory properties without causing cytotoxic effects.

DZ2002, an orally active, reversible, and low-cytotoxic type III SAHH inhibitor (Ki=17.9 nM), exhibits significant immunosuppressive activity. It effectively prevents experimental dermal fibrosis by reversing the profibrotic phenotype in multiple cell types, making it useful for studying autoimmune diseases like lupus syndrome and systemic sclerosis.

DL-Penicillamine (3-Sulfanylvaline) is a chelating agent recommended for the removal of excess copper in patients with Wilson's disease. DL-Penicillamine is only found in individuals that have used or taken this drug. It is the most characteristic degradation product of the penicillin antibiotics. It is used as an antirheumatic and as a chelating agent in Wilson's disease. From in vitro studies which indicate that one atom of copper combines with two molecules of DL-penicillamine. DL-Penicillamine also reduces excess cystine excretion in cystinuria. This is done, at least in part, by disulfide interchange between DL-penicillamine and cystine, resulting in the formation of penicillamine-cysteine disulfide, a substance that is much more soluble than cysteine and is excreted readily. DL-Penicillamine interferes with the formation of cross-links between tropocollagen molecules and cleaves them when newly formed. The mechanism of action of DL-penicillamine in rheumatoid arthritis is unknown although it appears to suppress disease activity. Unlike cytotoxic immunosuppressants, DL-penicillamine markedly lowers IgM rheumatoid factor but produces no significant depression in absolute levels of serum immunoglobulins. Also unlike cytotoxic immunosuppressants which act on both, DL-penicillamine in vitro depresses T-cell activity but not B-cell activity.
