  Extravascular Transport of Drugs in Tumor Tissue:  Effect of Lipophilicity on Diffusion of Tirapazamine Analogues in Multicellular Layer Cultures

  摘要：

  The extravascular diffusion of antitumor agents is a key determinant of their therapeutic activity, but the relationships between physicochemical properties of drugs and their extravascular transport are poorly understood. It is well-known that drug lipophilicity plays an important role in transport across biological membranes, but the net effect of lipophilicity on transport through multiple layers of tumor cells is less clear. This study examines the influence of lipophilicity (measured as the octanol-water partition coefficient P) on the extravascular transport properties of the hypoxic cytotoxin tirapazamine (TPZ, 1) and a series of 13 neutral analogues, using multicellular layers (MCLs) of HT29 human colon carcinoma cells as an in vitro model for the extravascular compartment of tumors. Flux of drugs across MCLs was determined using diffusion chambers, with the concentration-time profile on both sides of the MCL measured by HPLC. Diffusion coefficients in the MCLs (D-MCL) were inversely proportional to M-r(0.5) (M-r, relative molecular weight), although this was a minor contributor to differences between compounds over the narrow M, range investigated. Differences in lipophilicity had a larger effect, with a sigmoidal dependence of DMCL on log P. Correcting for M, differences, lipophilic compounds (log P > 1.5) had ca. 15-fold higher DMCL than hydrophilic compounds (log P < -1). Using a pharmacokinetic/pharmacodynamic (PK/PD) model in which diffusion in the extravascular compartment of tumors is considered explicitly, we demonstrated that hypoxic cell kill is very sensitive to changes in extravascular diffusion coefficient of TPZ analogues within this range. This study shows that simple monosubstitution of TPZ can alter log P enough to markedly improve extravascular transport and activity against target cells, especially if rates of metabolic activation are also optimized.

  N-苯基-N'-（2-氯乙基）脲（CEU）作为潜在的抗肿瘤药。第2部分：ω-羟基在与β-微管蛋白共价结合中的作用。

  摘要：

  微管蛋白是许多抗癌药物的靶标，包括N-苯基-N'-（2-氯乙基）脲（CEU）。与大多数抗β-微管蛋白剂不同，CEU是蛋白质单烷基化剂，通过其N'-（2-氯乙基）脲部分与β-微管蛋白同种型2秋水仙碱结合位点附近的氨基酸结合。继先前合成和有吸引力的N-（3-ω-羟烷基苯基）-N'-（2-氯乙基）脲在纳摩尔水平上表现出生长抑制活性后，我们研究了低级烷基和烷氧基对评估N-（3-ω-羟烷基苯基）脲的重要性羟基化基团和链长对细胞生长的抑制作用及CEU的作用机理。在这里，我们描述了两个新系列的CEU的制备，并显示除ω-羟基化的1f以外，最有效的CEU衍生物分别为2f和3e。

  Tubulin is the target of many anticancer drugs, including N-phenyl-N'-(2-chloroethyl)urea (CEU). Unlike most anti-beta-tubulin agents, CEUs are protein monoalkylating agents binding through their N'-(2-chloroethyl)urea moiety to an amino acid nearby the colchicine-binding site on beta-tubulin isoform-2. Following the previously synthesized and attractive N-(3-omega-hydroxyalkylphenyl)-N'-(2-chloroethyl)urea
