Abstract: The invention provides conjugate-based antifungal or antibacterial prodrugs formed by coupling at least one antifungal agent or antibacterial agent with at least one linker and/or carrier. The prodrugs are of formula: (i) (AFA)m-X-(L)n; (ii) [(AFA)m?-X]p-L; (iii) AFA-[X-(L)n?]q; or (iv) (AFA)m?-X, wherein: AFA is an antifungal agent or an antibacterial agent; L is a carrier; X is a linker; m ranges from 1 to 10; n ranges from 2 to 10; m? is 1 to 10; p is 1 to 10; n? is 1 to 10; and q is 1 to 10, provided that q? and n are not both 1; and m? is 1 to 10. The invention also provides nonaparticles comprising the conjugate-based prodrugs. Additionally, the invention also provides non-conjugated antifungal and antibacterial agents in the form of nanoparticles.

Abstract: Linking sequences which modulate cross-talk between modules of Type I polyketide synthases have been identified. Thus, arbitrarily chosen modules can be mixed and matched by supplying the appropriate linkers to obtain desired polyketide synthases and new polyketides. The modules are provided suitable linkers so that the polyketide chain is passed from one module to the other in the correct sequence. Synthetic peptides which mimic linkers can be used to inhibit the synthesis of polyketides. Kinetic channeling, both intrapolypeptide and interpolypeptide, of diketide intermediates in a Type I polyketide synthase can occur.

Abstract: Linking sequences that modulate cross-talk between modules of Type I polyketide synthases have been identified and methods for their use are described. Arbitrarily chosen modules can be mixed and matched by supplying the appropriate linkers to facilitate transfer of a growing polyketide chain between modules. Employing these techniques, new polyketide end products may be obtained.
