摘要:
In its many embodiments, the invention provides compounds of structural Formula (I): (I), and pharmaceutically acceptable salts thereof, wherein, ring A, R1, R2and R3are as defined herein, and pharmaceutical compositions comprising one or more such compounds (alone and in combination with one or more other therapeutically active agents). The invention further provides methods for the preparation and use of the compounds of the invention, or a pharmaceutically acceptable salt thereof, alone and in combination with other therapeutic agents, as antagonists of A2a and/or A2b receptors, and in the treatment of a variety of diseases, conditions, or disorders that are mediated, at least in part, by the adenosine A2a receptor and/or the adenosine A2b receptor.

An efficient synthesis of methyl nicotinates/6-halonicotinates by the domino isomerization of 4-propargyl/(3-halopropargyl)-5-methoxyisoxazoles under Fe(II)/Au(I) relay catalysis was developed. It was found that FeNTf2 is an effective catalyst for first step of the domino isomerization, transformation of isoxazole to 2H-azirine, which is compatible with Ph3PAuNTf2, catalyzing the second step.
Provided are a novel low-molecular-weight compound that suppresses production of induction type MMPs, particularly MMP-9, rather than production of hemostatic type MMP-2, as well as a prophylactic/therapeutic drug for autoimmune diseases or osteoarthritis. An amide derivative represented by the following formula (I)
wherein each symbol is as defined in the specification, or a pharmacologically acceptable salt thereof.

The application relates to triazole derivatives of the general Formula (I) that bind to Lysophosphatidic Acid Receptor 1 (LPAR1) and act as antagonists of LPAR1. The compounds are useful for the treatment of diseases and/or conditions through binding of LPAR1, including fibrosis and liver diseases such as non-alcoholic steatohepatitis (NASH), interstitial lung disease (ILD), or chronic kidney disease (CKD)

The present invention relates to a class of bifunctional chimeric heterocyclic compounds for targeted degradation of androgen receptors and use thereof, and specifically provides a compound of formula (I), or an isotopic compound thereof, or an optical isomer thereof, or a tautomer thereof, or a pharmacologically acceptable salt thereof, or a prodrug thereof, or a solvate thereof, wherein ARB is an androgen receptor recognition/binding part, L is a link part, and U is a ubiquitin protease recognition/binding part; and the three parts are connected by means of chemical bonds. The compound can perform the targeted degradation on androgen receptors in prostate cancer cells, and suppress the proliferation of the prostate cancer cells, and also show good metabolic stability and pharmacokinetic properties. The compound has good application prospect in the preparation of targeted chimeras for protein degradation of androgen receptors and in the preparation of drugs for treating the related diseases regulated by the androgen receptors.
