摘要:背景:脂肪酸与醇,尤其是多元醇(聚羟基醇)的酯已在合成油脂,合成润滑剂,化妆品,食品和油漆行业中得到了广泛应用.工业上或常规的酯化反应通过在均相性质的酸催化剂存在下使羧酸与醇缩合来进行的.由于其安全的操作性,稳定性,容易的回收和用于酯化反应的再循环能力,非均相/固体酸催化剂的开发已经引起了极大的科学兴趣.但是,已报道的方法已用于酸与一元醇的酯化反应.据我们所知,尚无关于使用石墨烯基碳催化剂将脂肪酸与多羟基醇酯化的报道. 方法:采用两步法合成所需的磺化氧化石墨烯(sgo),第一步包括将石墨氧化,然后在重氮化条件下用磺胺酸磺化以合成sgo,从而合成氧化石墨烯(go).使用5 Wt%的sgo作为催化剂在甲苯中于110oc进行脂肪酸与多羟基醇的酯化反应6小时. 结果:作为模型实例,进行了大量实验以优化2,2-二甲基-1,3-丙二醇(dmpd)与己酸(c6酸)酯化的反应参数.发现酯化的最佳条件是5

摘要:The present invention relates to methods of stimulating collagen synthesis and of smoothing or removing wrinkles, which comprise administering an effective amount of a benzoic acid derivative of formula (1) or a salt thereof, wherein X is -O- or -N(R4)- (R4 is H or the like), R1 is a C¿4-25?-alkyl or C4-25-alkenyl group, R?2¿ is H, OH, or a C¿1-6?-alkoxyl or C1-6-alkanoyloxy group, and R?3 is -OR5¿ or -N(R?6)R7 (R5? is H, or a C1-25-alkyl or C1-25-alkenyl group), and R?6 and R7¿ are individually H, or a C¿1-3?-alkyl or C1-3-alkenyl group, and use of this compound for agents for stimulating synthesis of collagen, and smoothing or removing wrinkles. This compound (1) stimulates collagen synthesis in human dermal fibroblasts and consequently smooths or removes wrinkles caused by aging and/or photoaging.

摘要:Dihydronepetalactone, a minor natural constituent of the essential oil of catmints ( Nepeta spp.) such as Nepeta cataria , has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.

摘要:This invention relates to novel compounds with skin lightening properties based on an aromatic hydrazine carboxyimidoamide structure, topical skin lightening compositions comprising the same and a method of skin lightening using the said compositions. In particular, the skin lightening benefit is selected from any one of the group consisting of treating melasma, treating post-inflammatory hyperpigmentation, treating age spots, treating dark spots and treating uneven skin tone. n Desired skin colour is a major unmet consumer need around the world and especially in Asia. Consumers particularly desire even skin colour, absence of age spots (solar lentigines), absence of hyperpigmentation and lighter overall skin tone. One solution is to use biological actives that reduce the activity of melanocyte cells in skin. These cells, present in the basal layer of the epidermis, make the dark coloured pigment melanin and export it, in small export vesicles called melanosomes, to the neighbouring keratinocytes. It is well described in the literature that compounds which reduce melanin synthesis when topically applied to the skin will reduce skin darkness over time and can generate a more even skin tone. n Tyrosinase is a very popular target for the regulation of melanocyte pigment production. However effective inhibitors of tyrosinase are bedevilled by safety issues causing, for example, melanocyte cell death, permanent depigmentation, irritation and allergic reactions. Often effective inhibitors kill melanocytes (for example hydroquinone) or cause sensitisation reactions. There is therefore a great need for safe and effective inhibitors of skin pigment production that work through an alternative safe mechanism. n The inventors have observed that selected compounds of the same generic structure inhibit the production of soluble melanin by B16 mouse melanoma cells without cell toxicity.
