By use of oligonucleotide-directed, site-specific mutagenesis, Pro327 in the lac permease of Escherichia coli has been replaced with Ala, Gly, or Leu. Permease with Ala at position 327 catalyzes lactose/H+ symport in a manner indistinguishable from wild-type permease. Permease with Gly at position 327, on the other hand, exhibits about one-tenth the activity of wild-type permease but catalyzes ...

The inhibition of squalene epoxidase by the allylamine antimycotic agents naftifine and compound SF 86-327 was investigated, with particulate enzyme preparations from the pathogenic yeasts Candida albicans and Candida parapsilosis and from rat liver. Both naftifine and compound SF 86-327 were potent inhibitors of the Candida epoxidases and showed apparently non-competitive kinetics with respect...

Based on the results of TAX 327, a nomogram was developed to predict the overall survival of metastatic castration-resistant prostate cancer (mCRPC) after first-line chemotherapy. The nomogram, however, has not been validated in an independent dataset, especially in a series out of clinical trials. Thus, the objective of the current study was to validate the TAX 327 nomogram in a community sett...

A bioassay with Trichophyton mentagrophytes is described for SF 86-327, an allylamine antifungal agent. SF 86-327 serum concentrations were measured by bioassay in 117 serum sampler from five patients receiving 500 mg/day. The peak, trough, and area under the concentration-time curve were determined after the first dose and at steady state. Drug accumulation occurred with prolonged therapy.
