Mevinic acid is reversible competitive inhibitors of HMG-CoA reductase (Ki in the range of 0.2-1 nM). Mevinic acid is a precursor of a Mevastatin (mevinic acid lactone) -- a hypolipidemic agent that belongs to the statins class. Mevastatin inactive until metabolized in the liver to the open-ring hydroxy acid (Mevinic acid). Mevastatin might be considered the first statin drug; clinical trials on mevastatin were performed in the late 1970s in Japan, but it was never marketed.

A small molecule, multi-target kinase inhibitor, 4SC-203 (formerly SC-71710), was being developed by 4SC AG for the treatment of cancer, with an focus on acute myeloid leukaemia. 4SC-203 selectively inhibits FMS-related tyrosine kinase 3 (FLT3/STK1), FLT3 mutated forms, and vascular endothelial growth factor receptors (VEGFRs). This may result in the inhibition of angiogenesis and cell proliferation in tumor cells in which these kinases are upregulated. FLT3 (FLK2), a class III tyrosine kinase receptor, is overexpressed or mutated in most B lineage and acute myeloid leukemias (AML). VEGFRs, tyrosine kinase receptors, are overexpressed in a variety of tumor cell types and play key roles in angiogenesis. 4SC has discontinued the development of 4SC-203 (formerly SC-71710), the lead in a series of Flt-3, VEGF protein kinase and aurora kinase A and B inhibitors, for the treatment of acute myeloid leukaemia (AML) as the personnel and financial resources have been allocated preferentially to the development of resminostat.

N-[2-[(2-amino-2-oxoethyl)-[3-(2-oxopyrrolidin-1-yl)propyl]amino]-2-oxoethyl]-2-[2-(2-fluorophenyl)ethylamino]-N-(2-methylpropyl)acetamide (BN201) is a small peptide molecule, a first-in-class neuroprotective compound. BN201 promotes the survival of cultured neural cells when subjected to oxidative stress or when deprived of trophic factors. BN201 promotes neuronal differentiation, the differentiation of precursor cells to mature oligodendrocytes in vitro, and the myelination of new axons. BN201 modulates several kinases participating in the insulin growth factor 1 pathway including serum-glucocorticoid kinase and midkine, inducing the phosphorylation of NDRG1 and the translocation of the transcription factor Foxo3 to the cytoplasm. In vivo, BN201 prevents axonal and neuronal loss, and it promotes remyelination in models of multiple sclerosis, chemically induced demyelination, and glaucoma. Bionure, a spin-off from Hospital Clínic de Barcelona that is based in California, is developing BN201 for multiple sclerosis, acute optic neuritis (AON) and glaucoma. BN201 was granted with orphan designation status for optic neuritis by the FDA. Optic neuritis is often an early sign of multiple sclerosis. The efficacy, safety, and capacity of the drug to cross the blood-brain barrier have been demonstrated in animal models, but the drug has not yet entered clinical testing.

ON-123300 is a potent and multi-targeted kinase inhibitor with potential application for brain tumor chemotherapy. ON123300 strongly inhibits Ark5 and CDK4, as well as growth factor receptor tyrosine kinases such as β-type platelet-derived growth factor receptor (PDGFRβ). ON123300 inhibited U87 glioma cell proliferation and reduced phosphorylation of Akt, yet it also unexpectedly induced Erk activation, both in a dose- and time-dependent manner that subsequently was attributed to relieving Akt-mediated C-Raf S259 inactivation and activating a p70S6K-initiated PI3K-negative feedback loop. ON123300 demonstrated high brain and brain tumor accumulation and favorable pharmacokinetic characteristics.

Methalthiazide is a diuretic and antihypertensive agent.

Remeglurant is a selective antagonist of subtype 5 metabotropic glutamate receptors (mGluR5). mGluR5 antagonists have a modulatory role in the control of glutamatergic neurotransmission. This drug was developed for treatment in drug-induced dyskinesia (an involuntary movement disorder). A phase 1 trial was conducted but no further development has been reported since 2016.
