The compound of the present invention has good oral absorption properties, and can be applied to oral treatment of human or animal B cell or plasma cell proliferative diseases and autoimmune diseases.

Abstract: A foldable nozzle assembly and a bidet are provided. The foldable nozzle assembly includes a nozzle body. The nozzle body is equipped with a nozzle base, and a limiting component is installed between the nozzle base and the nozzle body. A rotational component on the nozzle base allows for the pivotal attachment of a rotating base, which supports a nozzle. The nozzle can be folded onto the nozzle base using the limiting component and the rotational component, enabling the foldable functionality of the bidet nozzle, reducing space occupation, and facilitating storage. The invention features a simple structure, ease of use, and practicality.

Abstract: An optimal detection voltage obtaining method, a reading control method and an apparatus are provided.

Abstract: A tool and method for a faucet installation is disclosed. Both sides of the T-shaped flange are provided with screw holes, guide grooves, a first step, and a second step. A tightening screw is arranged in the screw hole, and the tightening screw is threadedly connected with the tightening component. The tightening screw controls the tightening part in the T-flange to rotate and unfold from the first step, and then fit in the guide groove and tighten upward, tighten and fix the T-flange in the faucet fixing hole of the sink, and then connect and fix the faucet with the fixing device to realize the operation and installation of the faucet on the front of the sink. The fixing device can be installed and fixed by rotating the two tightening screws in the positive direction.

Abstract: The invention describes a polymorph of (R)-methyl-2-(3-aminopiperidin-1-yl)-3-(2-cyanobenzyl)-4-carbonyl-3,4-dihydrothiophene[3,2-d]pyrimidine-6-carboxylic acid maleate and a preparation method therefor. The polymorph is a crystal having high stability and low hygroscopicity, and the crystal form is selected from crystal form A, crystal form B and crystal form C. Furthermore, the crystal form has a strong in-vivo hypoglycemic activity and can be used for the preparation of a novel drug for the treatment or prevention of diabetes mellitus type H and/or complications of diabetes mellitus type H.

Abstract: The invention relates to a salt form of (R)-methyl-2-(3-aminopiperidin-1-yl)-3-(2-cyanobenzyl)-4-carbonyl-3,4-dihydrothiophene[3,2-d]pyrimidine-6-carboxylic acid and a preparation method for the salt form. Also disclosed is a pharmaceutical composition of the formula I compound salt form.

Abstract: The present invention discloses 3D-structure of SARS-CoV Viral 3CL Protease obtained through molecular simulation. The 3D-structure is used as a drug target for screening the existing medical database CMC (Comprehensive Medicinal Chemistry, MDL Information System, Inc.), and a group of compounds which have the activity of inhibiting SARS-CoV virus 3CL Protease are found. Cinanserin was tested at molecular and viral levels, and it was found to be able to inhibit the SARS-CoV viral 3CL protease and SARS-CoV viruses. Cinanserin analogs were synthesized and tested at molecular and viral levels, they were found to be able to inhibit the SARS-CoV virus 3CL Protease and SARS-CoV viruses, and may be used for treating and/or preventing SARS-CoV virus infection.
