中文简介: | 药物发现,从概念到临床,是一个复杂而昂贵的过程,多年来涉及越来越多的人和资源。这一成本的一个主要组成部分是药物的损耗率,这些药物已达到开发阶段,但由于不良毒性或对目标疾病的疗效有限而失效。近年来,人们更加关注在发现过程的早期阶段解决磨损问题,并将研究重点从单纯基于对分离的靶蛋白的效力的策略转移。它从实用的、多学科的实验室工作开始,最终确定在大型跨国临床试验中评估的候选分子。随着开发工作的进行,该建筑群的供应需求不断增加,反映出成本不断上升。通常,从几毫克的化合物中识别出一次击中;初步药代动力学和药效测定通常需要几百毫克到几百克的物质,为了临床前安全性和药学评估,可能需要增加到公斤。当人体试验开始时,通常需要几十到几百公斤的重量;生产可能需要以吨为单位计量的数量。 本开放学习课程是从开放大学课程S827概念到临床的改编摘录。 |
课程简介: | Drug discovery, from concept to clinic, is a complex and expensive process involving the work of an escalating number of people and resources over many years. A major component of this cost has been the attrition rate of medicines that reach the development stage but then fail as the result of adverse toxicity or only limited effectiveness against the target disease. In recent years much greater attention has been paid to addressing the problems of attrition at an earlier stage in the discovery process and moving the focus of research away from a strategy based purely on potency against the isolated target protein. It begins with practical, multidisciplinary, laboratory work leading to the identification of candidate molecules that are evaluated in large multinational clinical trials. The escalating costs are mirrored by the increasing demand for supply of the compound as development work proceeds. Typically, a hit is identified from a few milligrams of compound; preliminary pharmacokinetic and efficacy determination will typically require hundreds of milligrams to grams of material, escalating to perhaps kilograms for preclinical safety and pharmacy evaluation. By the time human trials are initiated, tens to hundreds of kilograms are often necessary; production may entail quantities measured in tonnes. This OpenLearn course is an adapted extract from the Open University course S827 Concept to clinic. |
