Wang, Tao published the artcileDiscovery of the Human Immunodeficiency Virus Type 1 (HIV-1) Attachment Inhibitor Temsavir and Its Phosphonooxymethyl Prodrug Fostemsavir, Synthetic Route of 197958-29-5, the publication is Journal of Medicinal Chemistry (2018), 61(14), 6308-6327, database is CAplus and MEDLINE.
The optimization of the 4-methoxy-6-azaindole series of HIV-1 attachment inhibitors (AIs) that originated with 1 to deliver temsavir (3, BMS-626529) is described. The most beneficial increases in potency and pharmacokinetic (PK) properties were attained by incorporating N-linked, sp2-hybridized heteroaryl rings at the 7-position of the heterocyclic nucleus. Compounds that adhered to a coplanarity model afforded targeted antiviral potency, leading to the identification of 3 with characteristics that provided for targeted exposure and PK properties in three preclin. species. However, the phys. properties of 3 limited plasma exposure at higher doses, both in preclin. studies and in clin. trials as the result of dissolution- and/or solubility-limited absorption, a deficiency addressed by the preparation of the phosphonooxymethyl prodrug 4 (BMS-663068, fostemsavir). An extended-release formulation of 4 is currently in phase III clin. trials where it has shown promise as part of a drug combination therapy in highly treatment-experienced HIV-1 infected patients.
