  Inhibitors of Farnesyl Protein Transferase. 4-Amido, 4-Carbamoyl, and 4-Carboxamido Derivatives of 1-(8-Chloro-6,11-dihydro-5H-benzo[5,6]- cyclohepta[1,2-b]pyridin-11-yl)piperazine and 1-(3-Bromo-8-chloro-6,11- dihydro-5H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-yl)piperazine

  摘要：

  The synthesis of a variety of novel 4-amido, 4-carbamoyl and 4-carboxamido derivatives of 1-(8-chloro-6,11-dihydro-5H-benzo[5,6]cyclohepta[1,2-b]pyridin -11-yl)piperazine to explore the SAR of of this series of FPT inhibitors is described. This resulted in the synthesis of the 4- and 3-pyridylacetyl analogues 45a and 50a, respectively, both of which were orally active but were found to be rapidly metabolized in vivo. Identification of the principal metabolites led to the synthesis of a variety of new compounds that would be less readily metabolized, the most interesting of which were the 3- and 4-pyridylacetyl N-oxides 80a and 83a. Novel replacements for the pyridylacetyl moiety were also sought, and this resulted in the discovery of the 4-N-methyl and 4-N-carboxamidopiperidinylacetyl derivatives 135a and 160a, respectively. All of these derivatives exhibited greatly improved pharmacokinetics. The synthesis of the corresponding 3-bromo analogues resulted in the discovery of the 4-pyridylacetyl N-oxides 83b (+/-) and 85b [11S(-)] and the 4-carboxamidopiperidinylacetamido derivative 160b (+/-), all of which exhibited potent FPT inhibition in vitro. All three showed excellent oral bioavailability in vivo in nude mice and cynomolgus monkeys and exhibited excellent antitumor efficacy against a series of tumor cell lines when dosed orally in nude mice.

  A method of inhibiting Ras function and therefore inhibiting the abnormal growth of cells is disclosed. The method comprises the administration of a compound of Formula 1.0: 1 to a biological system. In particular, the method inhibits the abnormal growth of cells in a mammal such as a human being. Novel compounds of the formulas 2 are disclosed. Also disclosed are processes for making 3-substituted compounds of Formulas 5.0, 5.1, 5.2 and 5.3. Further disclosed are novel compounds which are intermediates in the process for making 3-substituted compounds of Formulas 5.0, 5.1, 5.2 and 5.3.

  本发明揭示了一种抑制Ras功能，从而抑制细胞异常生长的方法。该方法包括向生物系统中给予1.0:1化合物的管理。特别是，在哺乳动物如人类中，该方法抑制细胞异常生长。还揭示了公式2的新化合物。还揭示了制备公式5.0、5.1、5.2和5.3的3-取代化合物的过程。此外，还揭示了在制备公式5.0、5.1、5.2和5.3的3-取代化合物的过程中的新化合物，这些新化合物是中间体。
