The invention discloses an antibody-drug conjugate of Formula (I): (I) Ab-[L-Dn]x wherein: Ab comprises a broadly neutralizing anti-HIV antibody; L comprises a linker molecule covalently bonded to said broadly neutralizing anti-HIV antibody; D comprises one or more drugs comprising an HIV therapeutic compound covalently bonded to said linker molecule L, wherein said one or more broadly neutralizing anti-HIV antibodies Ab specifically bind to an HIV envelope glycoprotein and said one or more drugs D specifically bind to an HIV envelope glycoprotein; n is selected from 1-4; and x is selected from 1-12.
Optically Active Antifungal Azoles. III. Synthesis and Antifungal Activity of Sulfide and Sulfonamide Derivatives of (2R,3R)-2-(2,4-Difluorophenyl)-3-mercapto-1- (lH-1,2,4-triazol-1-yl)-2-butanol.
In an effort to find potent antifungal agents, optically active sulfur-containing triazole derivatives, sulfides (3) and sulfonamides (4), were prepared and evaluated for antifungal activity against Candida albicans in vitro and in vivo. The sulfides (3) were prepared by the reaction of (2R, 3R)-2-(2, 4-difluorophenyl)-3-mercapto-1-(1H, 1, 2, 4-triazol-1-yl)-2-butanol (1) with various heteroarylmethyl chlorides in the presence of sodium methoxide. The sulfonamides (4) were synthesized starting from the disulfide (15) in three steps including oxidation of the corresponding sulfenamides (17). Some of the sulfur-containing triazole derivatives (3, 4) showed strong protective effects against candidosis in mice.

Two-stage one-pot synthetic strategy for the key triazone-triazole intermediate of ensitrelvir (S-217622), an oral clinical candidate for treating COVID-19
was synthesized through a one-pottandemprocess (condensation and cyclization reaction) from commercially available chloroacetamide in a 72% yield. Then, the key triazone-triazole intermediate was obtained in a second one-potprocess by N-alkylation with triazone followed by highly selective N1-methylation with iodomethane in a 54% yield. In addition, two of the main process impurities were synthesized
