Provided are certain urea derivatives of amphotericin B (AmB) having improved therapeutic index compared to AmB. The compounds of the invention are less toxic than AmB and are useful to treat fungal infections. In certain embodiments the urea derivative of AmB is a compound represented by formula (I) or a pharmaceutically acceptable salt thereof: wherein, independently for each occurrence: R represents methyl, ethyl, propyl, or isopropyl; R' represents methyl, ethyl, propyl, or isopropyl; or R and R', taken together with the nitrogen atom to which they are attached, represent a radical of a cyclic secondary amine. Also provided are methods for making the urea derivatives of AmB.

An internal release agent includes at least one phosphodiester represented by the following general formula (1).
In the formula, R1 and R2 independently represent a hydrocarbon group having 1 to 30 carbon atoms, which is optionally substituted with at least one hydroxyl group, and R3 represents an alkylene group having 2 to 4 carbon atoms. A plurality of R3's may be the same as or different from each other. M represents a hydrogen atom, an ammonium ion, an alkali metal ion, or a monovalent/divalent alkali earth metal ion, and n is an integer of 1 to 60.
in the presence of primary amines or secondary α,ω-diamines has been applied to macroheterocyclic ringsynthesis. Starting from (hetero)diallylic systems, 12- to 36-membered polyheterocycles have been readily obtained in up to 56% yield. In addition, we show that the macrocyclic systems thus obtained can be debenzylated and that the resulting macrocyclic diamines undergo a second ring-closing bis(hy

Reaction of triethyl orthoesters with various N,N′-dialkyl-α,ω-alkanediamines in the presence of ammonium tetrafluoroborate or hexafluorophosphate, all in the same molar ratio, affords cyclic amidinium salts in excellent yields.
