N-Gene Research Laboratories is developing BGP-15 (NP-51), a small molecule, orally available, indirect Jun kinase (JNK) inhibitor and insulin sensitiser, for glycaemic control in patients with type-2 diabetes mellitus, and as an adjunct treatment for insulin resistance due to antipsychotics or obesity. In March 2002, N-Gene Research Laboratories granted Allos Therapeutics an exclusive license to its intellectual property surrounding BGP 15 in the US. BGP-15 has previously been used in clinical trials for the treatment of skeletal muscle pathology associated with Type 2 Diabetes (through insulin sensitization), Duchenne Muscular Dystrophy (DMD) and heart failure (through anti-inflammatory and anti-fibrotic mechanisms). Via its action as a modulator of the cytoprotective response to cellularstress, and specifically as a poly (ADP-ribose) polymerase (PARP) inhibitor, heat shock protein-inducer, membrane lipid therapeutic and an antioxidant inducer, BGP-15 has previously been shown to protect against skeletal muscle dysfunction, damage and wasting.

CB-5083 is a novel first in class, potent orally bio-available p97 inhibitor that disrupts cellular protein homeostasis and demonstrates anti-tumor activity in solid and hematological models. CB-5083 causes rapid and sustained accumulation of poly-ubiquitin in tumor xenografts after a single administration. CB-5083 showed activity to inhibit tumor growth in multiple rodent models of human cancer. Furthermore, CB-5083 appears to exhibit greater potency over current proteasome inhibitors that further validate targeting p97 and protein homeostasis in the treatment of cancer. CB-5083 is a potent inhibitor of endoplasmic reticulum associated degradation and induces a lethal unfodled protein response. CB-5083 recently began Phase 1 testing in relapsed/refractory or refractory multiple myeloma, and advanced solid tumors.

PLX8394 is a potent and selective inhibitor of B-Raf V600E (IC50 14 nM for WT and 3.8 nM for V600E mutant). Unlike vermurafenib, sorafenib and dabrafenib, PLX8394 does not cause paradoxical MAPK pathway activation. PLX8394 is under investigation in phase I/II of clinical trial for the treatment patients with advanced unresectable solid tumors.

CHIR 99021 is a selective, pyridimidine-based, glycogen synthase kinase 3 inhibitor that is effective at low nanomolar concentrations in enzyme assays and submicromolar concentrations in isolated cells and tissues. Chiron was developing CHIR 99021 for potential use in the treatment of type 2 diabetes mellitus. CHIR 99021 promoted insulin-mediated glucose uptake and increased glucose disposal in rodent models of diabetes. However, there has been no recent development reported.

Seviteronel (VT-464) is a 17,20-lyase selective inhibitor of CYP17A1, which plays key roles in adrenal and intratumoral de novo biosynthesis of androgens. The inhibition of 17,20-lyase activity by seviteronel (VT-464) is enough to reduce androgen levels, and its preserving of 17alpha-hydroxylase activity largely avoids interference with the production of other steroidal hormones. Seviteronel (VT-464) also has shown AR-antagonist activity independent of CYP17 enzyme inhibition. It is currently in phase 2 clinical trials as a therapeutic for castration-resistant prostate cancer patients.
