Abstract: A cell-based assay system in which the detection of the reporter gene activity, or secreted alkaline phosphatase (SEAP), is dependent upon the protease activity of the Hepatitis C virus NS3 gene product. This system can be used to assess the activity of candidate protease inhibitors in a mammalian cell-based assay system. The assay system is simpler than previously described assays due to the use of SEAP which allows the reporter gene activity to be quantified by measuring the amount of secreted gene product in the cell media by monitoring the conversion of luminescent or colorimetric alkaline phosphatase substrate.

Abstract: The present invention relates to processes for carrying out the following stereoselective microbial reduction of a racemic tetralone:
which comprises: contacting a compound of formula (I) with a microorganism, or an enzyme reduction system capable of accomplishing the subject reduction comprising an enzyme derived from said microorganism and a co-factor for said enzyme, and incubating the resulting mixture under conditions sufficient to yield the (4R) tetralol of formula (II) and to leave substantially unreacted the (4S) tetralone of formula (V) or “chiral tetralone.” The chiral tetralone can be used in the synthesis of sertraline. The subject process further optionally comprises the separation of the (4S) tetralone of formula (V) from the (4R) tetralol of formula (II). The (4R) tetralol can be recycled to produce the compound of formula (I) and the subject process repeated to result in even more of the desired (4S) tetralone of formula (V).
