摘要:
The present invention is directed to new bifunctional compounds and methods for treating HIV infections. The bifunctional small molecules, generally referred to as CDM-Hs, function through orthogonal pathways, by inhibiting the gp120-CD4 interaction, and by introducing cytotoxic moieties to gp120-expressing cells, thereby causing cell death and preventing cell infection and spread of HIV. It is shown that CDM-Hs bind to gp120 and gp-120 expressing cells competitively with CD4, and these compounds cause cell death of HIV-infected cells, thereby decreasing viral infectivity. Compounds and methods are described herein.

The present invention is directed to new bifunctional compounds and methods for treating HIV infections. The bifunctional small molecules, generally referred to as ARM- HI's, function through orthogonal pathways, by inhibiting the gpl20-CD4 interaction, and by recruiting anti-DNP antibodies to gpl20-expressing cells, thereby preventing cell infection and spread of HIV. It has been shown that ARM-HI's bind to gpl20 and gp-120 expressing cells competitively with CD4, thereby decreasing viral infectivity as shown by an MT-2 cell assay, the binding leading to formation of a ternary complex by recruiting anti-DNP antibodies to bind thereto, the antibodies present in the ternary complex promoting the complement-dependent destruction of the gpl20-expressing cells. Compounds and methods are described herein.

摘要:
Glucosepane is a structurally complex protein post-translational modification (PTM) believed to exist in all living organisms. Research in humans suggests that glucosepane plays a critical role in the pathophysiology of both diabetes and human aging; yet comprehensive biological investigations of this ‘metabolite have been’ greatly hindered by a scarcity of chemically homogeneous material available for study. Glucosepane possesses a unique chemical structure that incorporates a surprising, never-before-prepared non-aromatic tautomer of imidazole (hereafter termed an “iso-imidazole”), rendering it a challenging target for chemical synthesis. In this application, the inventors report the first total synthesis of glucosepane, enabled by the development of a novel one-pot method for preparation of the iso-imidazole core. The synthesis of the present invention is concise (8-steps starting from commercial materials), convergent, high-yielding (12% overall), and enantioselective. These results should prove useful to the art and practice of heterocyclic chemistry, and critical for the study of glucosepane and its role in human health and disease, especially the treatment of diabetic disorders or its impact on aging processes. Methods of synthesis, compounds obtained therefrom, pharmaceutical compositions and methods of treatment provide embodiments of the present invention.
