The present invention relates to crystalline forms of salts of Compound 1. The invention also relates to pharmaceutical compositions comprising the solid crystalline salts of Compound 1. The invention further relates to methods of treating a disease, disorder, or syndrome mediated at least in part by modulating in vivo activity of a protein kinase.

##STR00001##

The present disclosure relates to a cocrystal of pterostilbene and a coformer capable to form hydrogen bond interactions, to a process for the preparation thereof, and to its use as a medicament or a dietary supplement. The present disclosure also relates to a composition comprising the cocrystal.

The present disclosure relates to amorphous and crystalline forms of (R)—N-(4-chlorophenyl)-2-((1S,4S)-4-(6-fluoro-quinolin-4-yl)cyclohexyl)propanamide and its salts/cocrystals, solvates, and/or hydrates, processes for their production, pharmaceutical compositions comprising them, and methods of treatment using them.

Provided herein are compounds of the following Formula (I): or a pharmaceutically acceptable salt thereof. Methods for treating a diseases, disorders, or symptom by antagonizing muscarinic receptors, including specifically antagonizing muscarinic receptor 4 (M4), are also provided.

##STR00001##

A salt form and crystal form of a mutant IDHI inhibitor and a preparation method therefor.

##STR00001##

Disclosed are a crystal form of a compound (I) and a preparation method therefor, a pharmaceutical composition containing the crystal form, and the use of the crystal form in the preparation of a TYK2 inhibitor drug and a drug for treating psoriasis, systemic lupus erythematosus, and Crohn’s disease. The crystal form of compound I has one or more improved properties compared with the prior art and is of great value to the future optimization and development of the drug.

##STR00001##

The present invention provides a compound, or a pharmaceutically acceptable salt thereof, of formula (I):

##STR00001##

wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.26, R.sub.27, y, R, M, W, L, V, T, Y, J, K and A are as described herein, therapeutic uses of said compounds, uses of said compounds as research chemicals, a pharmaceutical composition and combinations comprising said compounds, and methods for manufacturing the compounds of the invention.

The invention provides non-centrosymmetric organic crystals which show exceptional self-healing properties. More particularly, the present invention provides non-centrosymmetric substituted imidazole and Dialkyl 4,4′-methylenebis(azanediyl)dibenzoate Crystals and a process for preparation thereof. These highly crystalline materials, when broken into pieces, can self-propel and re-join in the blink of an eye and repair themselves so precisely that they become indistinguishable from the undisturbed materials.

The present disclosure relates to: a) solid state forms of hydrobromide salts of Compound 1; b) pharmaceutical compositions comprising one or more solid state forms of hydrobromide salts of Compound 1, and, optionally, a pharmaceutically acceptable carrier; c) methods of treating tumors or cancers by administering one or more solid state forms of hydrobromide salts of Compound 1 to a subject in need thereof; and d) methods for the preparation of solid state forms of Compound 1.
