摘要:
Novel cephem derivatives represented by the general formula
in which the Acyl substituent is a group of the formula
wherein Ar is a lipophilic optionally substituted phenyl, naphthyl, pyridyl or benzthiazolyl group; R 1 is selected from certain optionally substituted aliphatic, aromatic, arylaliphatic or sugar moieties and R 2 and R 3 are each independently hydrogen, alkyl or aminoalkylcarbonylamino are gram-positive antibacterial agents, especially useful in the treatment of infectious diseases caused by methicillin-resistant Staphylococcus aureus (MRSA).
摘要:
This invention provides compounds having drug and bio-affecting properties, their pharmaceutical compositions and their use. In particular, the invention is concerned with azaindoleoxoacetyl piperazine derivatives of the present claim 1. These compounds possess unique antiviral activity, whether used alone or in combination with other antivirals, such as HIV protease inhibitors. More particularly, the present invention relates to compounds useful for the treatment of HIV and AIDS.
摘要:
The present invention provides pradimicin analogs of formula (II) which exhibit improved water solubility relative to parent compounds. These novel agents are useful in treatment of fungal infections. wherein R¹ is selected from the group consisting of H, methyl, and hydroxymethyl, and when R¹ is methyl or hydroxymethyl, the resulting amino acid has the D -configuration; R² is H or β-D-xylosyl; R³ is H or methyl; and R⁴ is selected from the group consisting of (C₂₋₅)alkenyl; (C₂₋₅)alkynyl; substituted (C₁₋₅)alkyl; substituted (C₂₋₅)alkenyl; wherein the substituent for both the alkyl and alkenyl is a group selected from the group consisting of, carboxy, (C₁₋₅)alkoxycarbonyl, carbamyl, (C₁₋₅)alkylcarbamyl, di(C₁₋₅)alkylcarbamyl, and sulfonyl; (C₁₋₅)alkanoyl substituted with a group selected from the group consisting of amino, (C₁₋₅)alkylamino, and di(C₁₋₅)alkylamino; L-glutamyl; formyl; benzyl; and p-tolylsulfonylcarbamyl; or a pharmaceutically acceptable salt thereof.
