    • Compounds having the general structure I are provided: X and Y are independently selected from the group consisting of CH2, N, NR9, C═O, C═S, S═O, SO2, S, O, (CR6R7)n, C(═O)—(CR6R7)n, and C(═S)—(CR6R7)n, where n is 1, 2, or 3. W is selected from the group consisting of and L is selected from the group consisting of N, O, S, S═O, SO2, C(O), NC(O), NC(S), OC(O), OC(S), C(NR10), C(NOR10), and a covalent bond. Z1, Z2, and Z3 are independently selected from the group consisting of substituted carbon and nitrogen. Compounds of formula I are agonists of the melanocortin-4 receptor (“MC-4r”) and therefore may have useful properties for controlling diseases related to MC-4r action in humans, such as obesity and type II diabetes.

    • Semi-synthetic glycopeptides that have antibacterial activity are based on modifications of the desmethyl-vancomycin scaffold, in particular, acylation of the amino substituent on the amino-substituted sugar moiety on this scaffold with certain acyl groups; and/or conversion of the acid moiety on the macrocyclic ring of this scaffolds to certain substituted amides. In addition, compounds of the invention include desmethyl-vancomycin scaffolds on which the acid moiety on the macrocyclic ring is converted to certain substituted amides and the amino substituent on the amino-substituted sugar moiety is alkylated with certain alkyl groups. Also provided are methods for synthesis of the compounds, pharmaceutical compositions containing the compounds, and methods of use of the compounds for the treatment and/or prophylaxis of diseases, especially bacterial infections.
