摘要:为了开发新型酪氨酸酶抑制剂,间苯二酚烷基葡糖苷7-12通过 Wittig 和/或 Horner-Wadsworth-Emmons 反应合成,其中 Koenigs-Knorr 糖基化是关键步骤.对于酪氨酸酶催化的氧化,观测到 7-12 的半数最大抑制浓度 (Ic 50 ) 为35.9-0.39 µm.还评估了羟烷基间苯二酚13-18和烷基间苯二酚19-24的酪氨酸酶抑制活性,以研究糖对其结构的影响.因此,Ic 50的13-18和19-24分别为 9.27-0.32 µm 和 1.58-0.53 µm.随着烷基链长度的增加,大多数衍生物变得更有效.C 2和c 3类似物之间的活性差距按顺序减小:间苯二酚烷基糖苷>羟烷基间苯二酚>烷基间苯二酚.这表明糖和羟基在与间苯二酚环相邻时会干扰功能.水溶性差的c 14类似物22 (Ic 50 = 0.81 µm) 与 C 10类似物21 (Ic

标 题:Process for the preparation of a 2-alkylphenol
发明人:STEINMETZ ARTHUR
权利人:RIEDEL DE HAEN AG
摘要:A 2-alkylphenol is prepared by reduction of a 2-acylphenol in the presence of a metallic catalyst. The reaction is carried out at a temperature of 80° to 200° C. and under a pressure of 10 to 100 bars, and a base metal, in particular copper, is used as a catalyst. It is particularly advantageous to use the catalyst in combination with a support. The hydrogenation of the acylphenol is advantageously carried out in the presence of an inert solvent. The process can be carried out continuously or discontinuously. The alkylphenols obtained are suitable for use in the synthesis of active substances having biocidal properties.

权利人:CHEMEX PHARMACEUTICALS INC
摘要:A grignard synthesis of pharmacologically active 1,4-bis(dihydroxyphenyl)butane and analogs, as well as novel intermediates, is provided, comprising preparing a grignard reagent preferably, a 3,4-dialkoxyphenyl propyl magnesium bromide, which may be reacted with carbonyl compounds to form intermediates of desired end products, said carbonyl compounds preferably being 3,4-dialkoxybenzaldehydes. The resulting alcohol is converted to a corresponding ether or siloxy compound, at the carbonyl site. The oxy-substituent is cleaved off; and the benzene ring or rings dealkylated to leave hydroxy substituents on the rings.

发明人:HEUER ANDREA; HÜPEDEN JENNIFER
权利人:BEIERSDORF AG
摘要:The invention relates to a topically applied preparation comprising a combination of substances including antimicrobial peptides (AMP), in particular cyclic peptide compounds based on the synthesis of thiazolidine and oxazolidine components, and skin-soothing substances such as menthoxypropanediol, substances to strengthen the skin barrier such as omega-6 fatty acids, and/or flavonoids such as licochalcone, which act synergetically and selectively against pathogenic bacteria, such as S. aureus and C. acnes , however not against skin-commensal bacteria, such as S. epidermidis . The preparations can be used advantageously for the treatment of acne or atopic dermatitis and to care for skin that has been damaged by acne or atopic dermatitis.
