Camptothecin-20(S)-O-propionate (CZ48) is a prodrug of camptothecin, an alkaloid isolated from the Chinese tree Camptotheca acuminata, with potential antineoplastic activity. Upon entry into cells, camptothecin-20(S)-O-propionate is hydrolyzed by esterases into the active form camptothecin. Camptothecin selectively stabilizes topoisomerase I-DNA covalent complexes, thereby inhibiting religation of topoisomerase I-mediated single-strand DNA breaks and producing potentially lethal double-strand DNA breaks when encountered by the DNA replication machinery. CZ48 is being investigated in clinical trials for the treatment of advanced solid tumors and lymphomas.

Conditions:

Belnacasan (VX-765), and its active metabolite VRT- 043198, is a novel and irreversible IL-converting enzyme/ caspase-1 inhibitor. VRT-043198 exhibits 100- to 10,000-fold selectivity against other caspase-3, -6 and -9. It exhibited potent inhibition against ICE/caspase-1 and caspase-4 with Ki of 0.8 nM and less than 0.6 nM, respectively. And VRT-043198 also inhibits IL-1β release from both PBMCs and whole blood with IC50 of 0.67 uM and 1.9 uM, respectively. Belnacasan inhibits the release of IL-1, IL-18 and IL-33. Belnacasan has shown to inhibit acute partial seizures in preclinical models and has shown activity in preclinical models of chronic partial epilepsy that do not respond to currently available compounds for epilepsy. In addition, it seems to reduce disease severity and the expression of inflammatory mediators in models of rheumatoid arthritis and skin inflammation. Belnacasan had been in phase II clinical trials by Vertex for the treatment of epilepsy. However, this study has been terminated later.

Monophosphothiamine is thiamine derivative used for the treatment of neuritis, polyneuritis, asthenic conditions (weakness), as an additional remedy for chronic blood circulation insufficiency, chronic gastritis accompanied by motor and secretory disorders functions of the stomach. Monophosphothiamine underwent metabolic phosphorylation to active metabolite thiamine pyrophosphate, that acts as a coenzyme in the different metabolic process.

R-1206 (also known as Elsulfavirine) is a phenylacetamide derivative patented by Roche Palo Alto LLC as non-nucleoside reverse transcriptase inhibitor (NNRTI) for treating retroviral infections. R-1206 is the prodrug of the active compound VM-1500A, a small molecule selective NNRTI, which prevents HIV replication. The antiviral activity of R-1206 is broad, with activity demonstrated towards various viral strains and clinical isolates of HIV, including those resistant to other NNRTIs. Furthermore, R-1206 was associated with a low probability of cross-resistance or resistance development, and a high genetic barrier to the development of resistant drug mutations. In clinical trials, R-1206 20 and 40 mg demonstrated superiority to efavirenz in terms of the effectiveness to reduce the level of viral load to 400 copies/mL after 12 weeks of therapy. R-1206 20 mg once daily is generally well tolerated in ART-naive HIV-1 infected patients.
8-Chloroadenosine-3',5'-cyclic-monophosphate (8-Cl-cAMP), an analog of c-AMP, is a novel antineoplastic agent. It has been shown to be effective against different human cancer cell lines modulating the cellular signal transduction pathway, thereby causing growth inhibition, cell differentiation, and apoptosis. 8-Cl-cAMP preferentially binds to the R2 subunit of protein kinase A (PKA) and induces rapid R2 up-regulation and eventual R1 subunit down-regulation. It has potent inhibitory effects on a wide variety of human cancer cell lines, with an IC50 ranging from 0.1 to 20 uM. The IC50 falls with the length of drug exposure. It can suppress c-myc and c-ras proto-oncogenes in vitro and in vivo. It was shown that 8-Cl-cAMP induces cell growth inhibition through AMP-activated protein kinase (AMPK) activation with p38 MAPK acting downstream of AMPK in this signaling pathway. 8-Cl-cAMP induced apoptosis, apparently through activation of the p38 MAPK pathway by inducing progressive phosphorylation of the p38 mitogen-activated protein kinase (MAPK), via activation of AMPK by its metabolite 8-Cl-adenosine. 8-Cl-cAMP does not significantly inhibit the growth of NIH 3T3 cells, rat kidney fibroblasts, mammary epithelial cells, or peripheral blood lymphocytes, nor does it inhibit the growth of parental cells whose progeny have been transformed. Such selectivity makes it an attractive candidate for cancer therapy suggesting that it should not cause the toxicity of conventional cytotoxic agents but should inhibit tumor growth. 8-Cl-cAMP has been evaluated in phase I/II clinical trials.

Rivenprost (ONO-4819) is a potent and selective EP4 receptor agonist. This compound can increase bone formation by stimulating osteoblast differentiation and function, possibly by modulating mesenchymal cell differentiation. Rivenprost has also been studied for its potential to prevent bone loss (in osteoporosis) and stabilize bone implants. Combined with risedronate, rivenprost may be an effective treatment for osteoporosis. A phase II study evaluating rivenprost in ulcerative colitis was terminated in 2009.

Cromakalim is an ATP-sensitive potassium (KATP) channel opener, which was studied for the treatment of gastric ulcer, hypertension and preventing a cardiomyopathy. But the development of this drug was discontinued due to heart lesions found in monkey chronic toxicity studies.
