Preclinical Pharmacokinetic and Pharmacological Studies of Antitumor and other Th

SRI国际为以下类型的临床前研究提供了持续的资源：(1)开发用于定量血浆、尿液、组织和其他生物基质中的化合物的敏感分析方法；(2)血浆稳定性和蛋白质结合研究，这些研究在化合物开发的早期阶段进行，以确保正确的样品处理，并有助于解释体内研究；(3)通过各种途径和时间表给药后对试验化合物进行药代动力学评估，包括通过各种途径确定生物利用度；(4)体内和各种体外系统（S9组分、微粒体、肝细胞、P450异构体、肝切片）中产生的药物代谢物的定量和鉴定；(5)化合物暴露对假定分子靶点的复合效应（药效学效应）的相关性。

SRI international provides a continuing resource for conducting the following types of studies with agents selected for preclinical development through the programs listed above: (1) development of sensitive analytical methods to quantify compounds in plasma, urine, tissues, and other biological matrices; (2) plasma stability and protein binding studies, which are conducted at an early stage of compound development to ensure proper sample handling and to aid in the interpretation of in vivo studies; (3) pharmacokinetic evaluation of test compounds following administration to animals by various routes and schedules, including a determination of bioavailability by various routes; (4) quantification and identification of drug metabolites generated in vivo and in various in vitro systems (S9 fractions, microsomes, hepatocytes, P450 isoforms, liver slices); and (5) correlation of compound effects on putative molecular targets (pharmacodynamic effects) with compound exposures.
