The invention relates to the use of aminoalcohol derivatives containing a urea functional group corresponding to the following formula:
in which:
R1 represents a linear or branched, saturated or unsaturated alkyl radical having from 8 to 22 carbon atoms;
R2 represents a hydrogen atom or a linear or branched, saturated alkyl radical having from 1 to 6 carbon atoms;
R3 represents a linear or branched, monohydroxylated or polyhydroxylated, saturated alkyl group having from 1 to 10 carbon atoms, in and for the preparation of cosmetic or dermatological compositions. These compounds are used in particular as moisturizing agents in care products for the skin or as conditioning agents in hair products.

The enzyme α‐methylacyl CoAracemase (AMACR) is involved in the metabolism of branched‐chain fatty acids and has been identified as a promising therapeutic target for prostatecancer. By using the recently available humanAMACR from HEK293 kidney cell cultures, we tested a series of new rationally designed inhibitors to determine the structural requirements in the acyl component. An N‐methylthiocarbamate
α-甲基酰基辅酶A外消旋酶(AMACR)参与支链脂肪酸的代谢,已被确定为前列腺癌的有希望的治疗靶标。通过使用最近从HEK293肾细胞培养物中获得的人AMACR,我们测试了一系列新的合理设计的抑制剂,以确定酰基成分的结构要求。一种N-甲基硫代氨基甲酸酯(K i = 98 n M),旨在模拟拟议的酶结合的烯醇酸酯,被发现是迄今为止报道的最有效的AMACR抑制剂。

were found to inhibitirreversibly both enzymes. Compound 10 was found to be a specific and selective inhibitor of human leukocyte elastase. In contrast to these, inhibitorsderivedfrom glycine methyl ester 1, D-valine methyl ester 4, and D-norvaline methyl ester 6 were found to be inactive. The results of the present study show that latent isocyanates derivedfrom appropriate aminoacids can serve as
fluoride as a ribosyl donor. The inhibition of the MraY transferase activity by the synthetized 11 urea-containing inhibitors was evaluated and 10 compounds revealed MraY inhibition with IC50 ranging from 1.9 μM to 16.7 μM. Their antibacterial activity was also evaluated on a panel of Gram-positive and Gram-negative bacteria. Four compounds exhibited a good activity against Gram-positive bacterial pathogens
