Cyclocondensation of the amine 151 with the ketoester 152 gave 153 that can be selectively alkylated to give 154 which upon benzylation and alkylation gave 155 as central nervous system agent (83EP90516) (Scheme 30).

Hansch and Leo [13] described the impact of Hpophihdty on pharmacodynamic events in detailed chapters on QSAR studies of proteins and enzymes, of antitumor drugs, of central nervous system agents as well as microbial and pesticide QSAR studies. Furthermore, many reviews document the prime importance of log P as descriptors of absorption, distribution, metabolism, excretion and toxicity (ADMET) properties [5-18]. Increased lipophilicity was shown to correlate with poorer aqueous solubility, increased plasma protein binding, increased storage in tissues, and more rapid metabolism and elimination. Lipophilicity is also a highly important descriptor of blood-brain barrier (BBB) permeability [19, 20]. Last, but not least, lipophilicity plays a dominant role in toxicity prediction [21].

A large number of compounds in which thiophene was fused to other heterocyclic rings have been investigated, notably in the central nervous system agents. For example, the benzodiazepine derivative (365) is reported to be more active than Clozapine in conditioned avoidance response tests in the rat (80JMC878). The activity of such fused-ring thiophenes has been reviewed (81JHC1277).
