Disclosed are derivatives of amphotericin B (AmB) characterized by improved therapeutic index compared to AmB. The AmB derivatives include C16 ureas, carbamates, and amides according to Formula (I); C3′-substituted C16 ureas, carbamates, and amides according to Formula (II); C16 acyls according to Formula (III); C2′epi-C16 ureas, carbamates, and amides according to Formula (IV); and C16 oxazolidinone derivatives according to Formula (V). Also disclosed are pharmaceutical compositions comprising the AmB derivatives, and therapeutic methods of using the AmB derivatives.
Described are RORγ modulators of the formula (I),
or stereoisomers, tautomers, pharmaceutically acceptable salts, solvates, or prodrugs thereof, wherein all substituents are defined herein. Also provided are pharmaceutical compositions comprising the same. Such compounds and compositions are useful in methods for modulating RORγ activity in a cell and methods for treating a subject suffering from a disease or disorder in which the subject would therapeutically benefit from modulation of RORγ activity, for example, autoimmune and/or inflammatory disorders.
The present invention provides compounds of formula I
and pharmaceutically acceptable salts thereof. The formula I compounds inhibit tyrosine kinase activity of such as TrkA, TrkB, TrkC, Jak2, Jak3 and CK2, thereby making them useful as antiproliferative agents for the treatment of cancer and other diseases.

Face off: The rutheniumcomplexes of a new axially chiral PNN ligand (L) are highly efficient in the presence of dimethylsulfoxide (DMSO) for hydrogenation of both functionalized and unfunctionalized tert‐alkyl ketones. DMSO is thought to narrow down the many possible complex stereoisomers into a single facial L/Ru complex, thus enhancing the reactivity, selectivity, and productivity.
