- Synthesis and Evaluation of Bifunctional Aminothiazoles as Antiretrovirals Targeting the HIV-1 Nucleocapsid Protein
-
Small molecule inhibitors of the HIV-1 nucleocapsid protein (NC) are considered as promising agents in the treatment of HIV/AIDS. In an effort to exploit the privileged 2-amino-4-phenylthiazole moiety in NC inhibition, here we conceived, synthesized, and tested in vitro 18 NC inhibitors (NCIs) bearing a double functionalization. In these NCIs, one part of the molecule is deputed to interact noncovalently with the NC hydrophobic pocket, while the second portion is designed to interact with the N-terminal domain of NC. This binding hypothesis was verified by molecular dynamics simulations, while the linkage between these two pharmacophores was found to enhance antiretroviral activity both on the wild-type virus and on HIV-1 strains with resistance to currently licensed drugs. The two most interesting compounds 6 and 13 showed no cytotoxicity, thus becoming valuable leads for further investigations.

PCT No. PCT/JP98/01778 Sec. 371 Date Dec. 17, 1998 Sec. 102(e) Date Dec. 17, 1998 PCT Filed Apr. 17, 1998 PCT Pub. No. WO98/47887 PCT Pub. Date Oct. 29, 1998The invention relates an epoxysuccinamide derivative represented by a formula (I): wherein R1 represents a hydrogen atom, an alkyl or aminoalkyl group, R2 represents an aminoalkyl group which May be substituted, an aryl group which may be substituted, a heterocyclic group which may be substituted, an aralkyl group which may be substituted, or an alkyl group substituted by a heterocyclic ring which may be substituted, or R1 and R2 may form a nitrogen-containing heterocyclic ring, which may be substituted, together with the adjacent nitrogen atoms, and R3 and R4 are the same or different from each other and independently represent a hydrogen atom, or an alkyl or aralkyl group, or a salt thereof, a preparation process thereof, and a medicine comprising such a derivative or salt as an active ingredient. This compound has a specific inhibitory activity for cathepsin L and family enzymes thereof, and is useful as an agent for preventing and treating metabolic osteopathy such as osteoporosis and hypercalcemia.
