专利号:US-4451565-A 优先权日:1981-03-10 标 题:Enzyme-mediated synthesis of esters and lactones 发明人:GATFIELD IAN; SAND THEODOR 权利人:HAARMANN & REIMER GMBH 摘要:In the enzyme-mediated synthesis of an ester or lactone from at least one carboxylic acid of the formula R-CH2-CH2-COOH wherein R is a hydrogen atom, or a hydrocarbon radical which has 1 to 21 carbon atoms and which can be optionally substituted by hydroxyl groups or alkoxy groups with 1 to 10 carbon atoms, with at least one primary or secondary alcohol having 1 to 15 carbon atoms, the improvement which comprises employing as the enzyme the esterase from Mucor miehei and effecting the synthesis in the absence of water. Advantageously, the synthesis is effected at about room temperature, the mol ratio of carboxylic acid to alcohol is from about 1:1 to 1:1.1, and the enzyme is used in a quantity of about 3 to 20% by weight of the carboxylic acid. The absence of water facilitates recovery, as by distillation.

A structure of a 3,4-fused seven-membered nitrogen heterocyclic oxindole is provided in the present invention. A method for synthesizing same is also provided, comprising the following steps: reacting propargyl alcohol containing an isatin framework with a nucleophile under specific conditions to prepare a 3,4-fused seven-membered nitrogen heterocyclic oxindole. A pharmaceutical composition is provided in the present invention. Also provided in the present invention is an application of a 3,4-fused seven-membered nitrogen heterocyclic oxindole in the preparation of a drug for treating cancer. Provided in the present invention is a method for efficiently synthesizing 3,4-fused seven-membered nitrogen heterocyclic oxindoles having different structures. This is the first time achieving efficient synthesis of bioactive molecules containing both benzazepine and 3,4-fused heterooxidized oxindole structures on the basis of a hydrogen migration strategy.
专利号:US-2024082118-A1 优先权日:2021-05-19 标 题:Topical compositions and methods of preparing the same 发明人:ABRAMOVICH SAGI; AVIDOR GAL; LANDA BENZION 权利人:LANDA LABS 2012 LTD 摘要:There is disclosed a composition comprising a water-insoluble thermoplastic compound capable of stimulating collagen synthesis (CSSC), the CSSC having a molecular weight of more than 0.6 kDa and being dispersed in a polar carrier as nano-elements having an average diameter of 200 nm or less and a viscosity of 107 mPa·s or less.
