先導(dǎo)化合物 Lead Compound -生物名詞

通過優(yōu)化藥用減少毒性和副作用可以使其轉(zhuǎn)變?yōu)橐环N新藥的化合物。一旦通過基因組學(xué)和藥理學(xué)方法發(fā)現(xiàn)和證實(shí)了一個(gè)有用的治療靶子,識(shí)別先導(dǎo)化合物是新藥開發(fā)的第一步。一般的,很多潛在化合物被篩選,大量緊密結(jié)合物被識(shí)別。這些化合物然后經(jīng)過一輪又一輪地增加嚴(yán)格性的篩選來決定它們是否適合于先導(dǎo)藥物優(yōu)化。一旦掌握了很多先導(dǎo)物,接下來就進(jìn)入優(yōu)化階段,這需要做三件事:應(yīng)用藥物化學(xué)提高先導(dǎo)物對(duì)靶子的專一性;優(yōu)化化合物的藥物動(dòng)力性能和生物可利用率;在動(dòng)物身上進(jìn)行化合物的臨床前的試驗(yàn)。

A compound that could potentially be converted to a new drug by optimizing its beneficial effects and minimizing its toxicity and side effects. Identifying lead compounds (typically by high-throughput screening) is the first step in the drug discovery process once a useful therapeutic target has been identified and validated through genomics and pharmacology. Typically, many potential compounds are screened (the primary screen) and numerous tight-binders (hits) are identified. These compounds are then taken through successive rounds of screening (secondary screens) of increasing stringency in order to determine their suitability for lead optimization. Once a handful of leads have been identified in this way, they are taken into lead optimization, which entails three things; the application of medicinal chemistry to improve the hit’s specificity to the target, optimization of the compound’s pharmacokinetics and bioavailability (ability to be metabolized by the body and to travel to its designated receptors in the afflicted cells and tissues), and the testing the compound in pre-clinical studies in animals.
