PX-102 is a methoxyphenylcyclopropane derivative patented by Phenex Pharmaceuticals AG as Farnesoid X receptor agonists useful in the treatment and prophylaxis of FXR-mediated diseases. The Farnesoid X Receptor (FXR) is a bile acid receptor which when activated by Px-102 has a profound positive impact on cholesterol, triglyceride and glucose metabolism in liver and intestine. In preclinical studies, Px-102 potently reduces intestinal uptake of neutral lipids and cholesterol and at the same time enhances the excretion of these lipid species. In addition, Px-102 improves hepatic insulin sensitivity and shows massive hepatoprotective effects in animal models of liver cirrhosis or fibrosis. Phenex Pharmaceuticals completes a phase I trial in Healthy volunteers in Germany in 2012 and no further development report has been published.

AMG 337 is an oral, small molecule, ATP-competitive, highly selective inhibitor of the cell surface enzyme called c-Met, which, when dysregulated, stimulates cancer cell scattering, invasion and protection from apoptosis. AMG 337, currently in Phase 2 development for the treatment of gastric and esophageal adenocarcinoma. In addition, recently was shown, that AMG 337 a promising and novel therapeutic strategy for targeting hepatocellular carcinomas with a dependence on HGF/MET signaling.

4-Demethyl-4-cholesteryloxycarbonylpenclomedine (DM-CHOC-PEN), a non-neurotoxic derivative of penclomidine, is under development by Dekk-Tec for the intravenous treatment of solid tumours. DM-CHOC-PEN is a cholesterol carbonate derivative of 4-demethylpenclomedine with potential antineoplastic alkylating activity. Upon intravenous administration of 4-demethylcholesteryloxycarbonylpenclomedine, the carbonium moiety binds to and alkylates DNA at the N7 guanine position, thereby causing DNA crosslinks. This prevents DNA replication, inhibits cellular proliferation and triggers apoptosis. In addition, due to its lipophilic cholesteryl moiety this agent is able to cross the blood brain barrier (BBB) and therefore can be given intravenously compared to other alkylating agents that need to be given intra-cranially. DM-CHOC-PEN has undergone a Phase I study (allowed enrollment of subjects with advanced cancer +/- CNS involvement) and is being evaluated in a Phase II trial in subjects with advanced cancer involving the brain. DM-CHOC-PEN has completed Phase I/II trials in humans with primary and secondary tumors involving the brain with success. Complete remissions in both primary astrocytoma and metastatic lung and leukemia malignancies.Impressive objective responses and improved PFS/overall survival have been observed in subjects with NSCLC involving the CNS.
