Also disclosed is a method for treating skin diseases or disorders associated with anti-tumor agents by the compound.

Abstract: A method for treating chemotherapy-related gastrointestinal side effects, in particular, relating to use of a CDK inhibitor in preparation of a drug. The drug is used for preventing, alleviating and/or treating the chemotherapy-related gastrointestinal side effects on a subject. The CDK inhibitor comprises a CDK1 inhibitor, a CDK2 inhibitor, a CDK3 inhibitor, a CDK4 inhibitor, a CDK5 inhibitor, a CDK6 inhibitor, a CDK7 inhibitor, a CDK 8 inhibitor, and/or CDK9 inhibitor. A chemotherapeutic agent may be selected from fluorouracil, oxaliplatin, topotecan, irinotecan, tetrahydrofolate, docetaxel, and the like. The gastrointestinal side effects comprise diarrhea, constipation, and the like.

Abstract: A compound and method may treat chemotherapy-associated gastrointestinal side effects. A compound of formula (I) or a pharmaceutically acceptable salt thereof in the preparation of a medicament: may be used for preventing, alleviating, and/or treating gastrointestinal side effects associated with chemotherapy in a subject. A method may use such a compound to treat chemotherapy-associated gastrointestinal side effects.

Abstract: A JAK inhibitor may be used in preparation of a medicament. The medicament may be used for preventing and/or treating a disease or condition associated with an antitumor agent in a subject. A pharmaceutical composition may include the JAK inhibitor as may a kit. The JAK inhibitor may include a compound of formula (I) or a pharmaceutically acceptable salt thereof: Q, X, Y, and Z being independently N or C, and R1, R2 and R3 being independently a 5-6-membered aromatic ring, 5-6-membered heteroaromatic ring, 5-6-membered cycloalkyl, 5-6-membered heterocycloalkyl, amino, or amido, the aromatic ring, heteroaromatic ring, cycloalkyl, and/or heterocycloalkyl being optionally substituted by a substituent.

Abstract: A method for preparing an iminodisuccinate chelating agent, wherein a reaction comprising raw material A, raw material B, an alkali metal hydroxide, and water is carried out under ambient pressure, and at a pH in the range of 6-12 and a reaction temperature ranging from 65° C. to a boiling reflux temperature, and the mixed liquid obtained after the reaction is a mixture containing the iminodisuccinate chelating agent. The raw material A is a compound capable of obtaining a maleate through alkaline hydrolysis; and the raw material B is a compound capable of obtaining an aspartic acid through alkaline hydrolysis. With mild reaction conditions, a short reaction time and a high reaction yield, the preparation method is able to shorten the production process, improve the production efficiency, and reduce the production cost, and it is truly a preparation method which is highly efficient, environmentally friendly, and extremely suitable for industrial scale production.
