The present invention relates to a new compound that can inhibit an anoctamin 6 protein, a composition comprising the compound, a method for preparing the compound, and a method for using the compound or composition.

The present invention discloses a phosphine nitrogen ligand with multiple chiral centers and its synthesis method and application. The ligand has the axial chirality of a biaryl skeleton and the central chirality of a chiral amine. The chiral ligand is synthesized from commercially available raw materials through a simple five-step reaction, and the resulting diastereomer can be separated by simple column chromatography or recrystallization. The chiral phosphine nitrogen ligand synthesized by the present invention can catalyze the asymmetric three-component coupling reaction of terminal alkynes, aldehydes and amines, and realize the efficient preparation of chiral propargyl amines with high optical activity.

The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof:
X-A-Y-L-R  (I)
which inhibit the protein(s) encoded by hepatitis B virus (HBV) or interfere with the function of the HBV life cycle of the hepatitis B virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HBV infection. The invention also relates to methods of treating an HBV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.

The present invention provides compounds, pharmaceutically acceptable compositions thereof, and methods of using the same for the modulation of one or more SWI/SNF-related matrix associated actin dependent regulator of chromatin subfamily A (SMARCA) and/or polybromo-1 (PB-1) protein via ubiquitination and/or degradation by compounds. The compounds are bifunctional molecules that link a cereblon-binding moiety to a ligand that binds SMARCA and/or PB1 proteins.
