The present invention relates generally to the field of pharmaceuticals and cosmetics. More specifically, the present invention pertains to certain N-(pyrid-4-yl)amides and N-(pyrimidin-4-yl)amides of formula (1) which are potent modulators (e.g., inhibitors) of an androgen receptor, and which are useful, for example, in therapy, for example, in the treatment of a dermatological disease or disorder; a disease or disorder of the sebaceous gland(s); acne; hyperseborrhoea; oily skin; seborrhoeic dermatitis; hyperpilosity or hirsutism; atopic dermatitis; or androgenic alopecia; especially acne. The present invention also relates to compositions (e.g., pharmaceutical compositions, cosmetic compositions) comprising the compounds; methods of preparing the compositions; methods of modulating (e.g., inhibiting) an androgen receptor using the compounds and/or compositions; and medical and/or cosmetic use of the compounds and compositions.

In this work, the synthesis and solid-statestructure of a lithium borate with 2,2-dipropylglycolato (GlyPr2) ligand has been described. The desired lithium borate as well as previously reported borates with methyllactato (ML) and mandelate (Man) ligands could be synthesized rapidly and cleanly by using LiBH4 as a reagent in THF. The solid-statestructures of the THF- and glyme-solvates of LiB(GlyPr2)2

Es wird ein neues Verfahren zur Herstellung von E-2-Propyl-2-pentensäure sowie von deren physiologisch verträglichen Salzen beschrieben, bei dem Di-n-propylketoncyanhydrin als Ausgangsverbindung verwendet wird. Die Verbindung wird entweder
a) mit Thionylchlorid dehydratisiert und das gebildete Säurenitril anschließend mit einem stöchiometrischen Überschuß von Kaliumhydroxid in Glycerin verseift oder
b) zunächst in die 2-Hydroxy-2-propylpentansäure überführt und diese anschließend in Gegenwart einer weniger als stöchiometrischen Menge eines tertiären Amins bei einer Temperatur von mindestens 200°C dehydratisiert.
Die freie Säure wird gegebenenfalls,vorzugsweise unter Verwendung der entsprechenden Salze der Kohlensäure in wäßriger Acetonlösung,in die Salzform überführt.
描述了一种制备 E-2-丙基-2-戊烯酸及其生理上可接受的盐类的新工艺,其中使用二-正丙基酮氰醇作为起始化合物。该化合物可以是
a) 用亚硫酰氯脱水,形成的酸性腈随后在甘油中用过量的氢氧化钾进行皂化,或
b) 首先转化为 2-羟基-2-丙基戊酸,然后在低于一定量的叔胺存在下,在 至少 200°C 的温度下脱水。
游离酸可选择转化为盐形式,最好使用丙酮水溶液中相应的碳酸盐。
