(S)-Ketoprofen, a dual COX1/2 inhibitor, can be used as a nonsteroidal anti-inflammatory drug to treat arthritis-related inflammatory pains. Ketoprofen is photolabile and undergoes degradation when irradiated by sunlight to induce various skin diseases [1].
In vitro: The combination of UVB irradiation with ketoprofen dose-dependently induced the cytotoxicity and suppressed DNA synthesis in HaCaT cells. UVB-irradiated KP inhibited the cell growth and induced G2/M cell cycle arrest by regulating the levels of cdc2, cyclin B1, Chk1, Tyr15-phosphorylated cdc2 and p21. The DAPI staining results has revealed that KP accentuated the apoptotic response to UVB radiation in HaCaT cells [1].
In vivo: In a placebo-controlled, double-blind study in the rhesus monkeys Macaca mulatta with periodontal disease, administeration of KP at 1% level in suitable topical vehicles to the gingiva once daily at a standard dose of 1.8 ml per monkey for 6 months effectively inhibited GCF-LTB4 and GCF-PGE2 and positively altered alveolar bone activity [2]. Ketoprofen at a dose of 3.63 mg/kg bwt (phenylbutazone equimolar dose) showed significant analgesic effects and reduced hoof pain and lameness to a greater extent [3]. Treatment with Ketoprofen (40 and 80 mg/kg diet) greatly reduced the incidence of transitional cell carcinoma of the urinary bladder by >70% from that seen in dietary mice [4].

求助各位前辈，我最近在合成的化合物水溶性很好，非常好，以至于可以随便溶解在水里，它的六氟磷酸盐也可以随意溶解在水里（大于50uM），细胞成像实验显示它根本进不去细胞，求问有没有啥方法包裹一下让它进去？我搜了一下文献，感觉多数是把脂溶性特别好的东西包裹一下弄进去的，也许是搜索姿势不对没找到我需要的答案，**点拨啊！！！
求助各位大神，现在想购买小分子数据库，求大神推荐。
我知道的免费的数据库有zinc
求推荐哪家公司或者研究所的小分子数据库可以购买，十分感谢！！！！！！
求助大家，小分子药物最新专利申请情况跟踪，之前听别人说可以在一个网站可以导出这个信息。
不知哪位大侠知道，告知一下，不胜感激！
就是蛋白质分子的小片断
是氨基酸形成的
一、首先你要明白肽是什么...........................肽是氨基酸通过酰胺键结合而成的东西.........
二、你要明白氨基酸是什么..........................氨基酸是构成蛋白质的基本单位，多种氨基酸结合为长肽链，几条长肽链再盘旋就形成了蛋白质......................
三、关于小分子肽、短肽、多肽、寡肽.......其实都是肽.......区别只是由多少个氨基酸构成而已............
所以，你的问题可以很粗暴地理解为“蛋白质对人体有没有副作用”.......
如果你营养足够的情况下，再补充这个，会导致营养过剩，从而加重身体代谢的负荷............类似就是这样子的了...........小分子肽，一般现在用于化妆品上比较多（一ye子.植物肽面膜就是这个）.......小分子肽（可以简单理解为纳米胶原蛋白），这比蛋白质（也可以粗暴理解为胶原蛋白）更加容易吸收......而用在食品上，要视乎是何种小分子肽了.....大豆肽、花生肽、大米肽....不同的肽有不同的功效.......主要可以改善风味、改善吸收、增强胃肠道功能等等.......
有机的是有机化合物的简称,它指的是含碳化合物.
但是,有四大类常见物质一般不作为有机物处理：
1、碳的氧化物,如CO和CO2.
2、碳酸及其盐,如CaCO3.
3、金属碳化物,如CaC2.
4、拟卤素及其化合物,如(CN)2与KSCN.
水的化学式为H2O,它不含有碳元素,故不是有机物.
但若所描述的水不是化学意义的水,而是自然界存在的天然水,那么,水中会溶有一定量的有机物.
