Specifically, a compound of formula (I), a preparation method therefor, a pharmaceutical composition containing the compound, and uses thereof as a regulator the of GABA.sub.A receptor for treating depression, convulsion, Parkinson's disease, and nervous system diseases are described, wherein the substituents of the formula (I) are as defined in the description. ##STR00001##

Described herein are steroid or steroid-like compounds including at least one isonitrile group and which inhibit the activity of a cytochrome P450 enzyme, as well as compositions including the compounds. Also included are methods of inhibiting activity of a cytochrome P450 in a subject having a steroid-responsive cancer, a Mycobacterium tuberculosis infection, a fungal infection, or a trypanosome infection, the method comprising administering to the subject the compound including at least one isonitrile group or a pharmaceutically acceptable salt thereof, in an amount effective to inhibit the CYP activity in the subject.

Described herein protein drug conjugates and compositions thereof that are useful, for example, for the target-specific delivery of drugs to cells. By administering these compounds, compositions, and conjugates as described herein to specific target cells, side-effects due to non-specific binding phenomena, for example, to non-target cells are reduced. In certain embodiments, compounds, compositions, and conjugates are provided, which include hydrophilic residues in linker-payloads and protein conjugates thereof.

This disclosure relates to progesterone phophate derivatives and uses related thereto. In certain embodiments, the disclosure relates to compounds disclosed herein and uses for managing inflammation such as those resulting from traumatic brain injury or stroke.

This application is directed to the use of aminosteroid compounds for the selective inhibition of the enzyme PTP1B in a mammal for the treatment of diabetes.

Described herein protein drug conjugates and compositions thereof that are useful, for example, for the target-specific delivery of drugs to cells. By administering these compounds, compositions, and conjugates as described herein to specific target cells, side-effects due to non-specific binding phenomena, for example, to non-target cells are reduced. In certain embodiments, compounds, compositions, and conjugates are provided, which include hydrophilic residues in linker-payloads and protein conjugates thereof.

Disclosed herein are drug delivery systems and methods for locally delivering therapeutic agents, and methods for using such drug delivery systems for the treatment of diseases.

Prodrugs of neurosteroid analogs are disclosed. Pharmaceutical formulations containing the prodrugs are also disclosed. Additionally, methods of treating a condition, disorder, or disease using the prodrugs or their pharmaceutical formulations are disclosed.
