TLR2 MODULATOR COMPOUNDS, PHARMACEUTICAL COMPOSITIONS AND USES THEREOF

The present disclosure relates to compounds which modulate the activity of Toll-like receptor (TLR) proteins, including agonists or activators, partial agonists, and antagonists. Of particular interest of compounds that modulate the activity of TLR2, as well as methods of using such compounds to treat cancer and other disorders associated with a TLR2 pathway.

BICYCLIC HYDROXAMIC ACIDS USEFUL AS INHIBITORS OF MAMMALIAN HISTONE DEACETYLASE ACTIVITY

A compound of formula (Ia) or (Ib) or a pharmaceutically acceptable salt thereof. The compound is an inhibitor of a histone deacetylase, and as such is useful in terepy, e.g. in the treatment of autoimmune disorders, mental disorders, neurodegenerative disorders, and hyperproliferative disorders.

NADPH OXIDASE 4 INHIBITORS

The invention relates to 2,5-disubstituted benzoxazole and benzothiazole derivatives of Formula (I) Formula (I) wherein L, X, Y, and ring (A) are as described in the description, their preparation and their use as pharmaceutically active compounds. Said compounds may be useful for the prevention or treatment of diseases or disorders associated with impaired reactive oxygen species (ROS) production, and/or for the prevention or treatment of various fibrotic diseases.

PIPERIDINE DERIVATIVES OR SALTS THEREOF

[Problem] To provide a compound which can be used for treating diseases in which a calcium sensing receptor (CaSR) participates, particularly hyperparathyroidism. [Means for Resolution] It was found that a novel piperidine derivative which is characterized in that one of a 3-position and a 4-position is substituted with an aminomethyl group substituted with an arylalkyl group or the like and the other position is substituted with aryl, heteroaryl or the like, or a salt thereof, has an excellent CaSR agonistic regulatory action, and also has excellent selectivity with a CYP2D6 inhibitory action having a possibility of causing drug interaction. Based on the above, this novel piperidine derivative is useful as a therapeutic agent for diseases in which CaSR participates (hyperparathyroidism, renal osteodystrophy, hypercalcemia, and the like).

Facile rearrangements of alkynylamino heterocycles with noble metal cations

A number of 2-(alkynylamino)-substituted heterocycles have been synthesized. These heterocycles rearrange in the presence of silver(I) and gold(I) salts to give novel 2H-pyrimido[2,1-b]benzoxazoles, 2H-pyrimido[2,1-b]benzothiazoles, and a 2H-pyrimido[2,1-b]benzoselenazole. Two of the the 2H-pyrimido[2,1-b]benzoxazoles were isolated in good yield. The kinetics of the silver tetrafluoroborate-catalyzed rearrangements of selected (alkynylamino)benzoxazoles and benzothiazoles have been examined by 1H NMR in CD3CN. Factors affecting the electron densities of the triple bond and of the nitrogen atom in the heterocycle are important in influencing the rate of rearrangement.
