• New pyrrolobenzothiazepine derivatives as molecular probes of the ‘peripheral-type’ benzodiazepine receptor (PBR) binding site

  A number of new pyrrolobenzothiazepine derivatives and a pyrrolobenzothiazocine derivative have been synthesized and evaluated for their affinity towards the 'peripheral-type' benzodiazepine receptor (PER). The new compounds were tested in rat cortex, a tissue expressing a high density of mitochondrial PER. Some of the pyrrolobenzothiazepines exhibited IC50 values in the low nanomolar range as measured by the displacement of [H-3]PK 11195 binding. Compound 4i was found to be the most potent ligand for this receptor in the pyrrolobenzothiazepine subgroup with an IC50 practically identical to that determined for PK 11195. Structure-affinity relationships (SARs) have been developed to elucidate the topology of the PER binding site.
• Pyrrolobenzothiazepinones and Pyrrolobenzoxazepinones:  Novel and Specific Non-Nucleoside HIV-1 Reverse Transcriptase Inhibitors with Antiviral Activity

  Two novel classes of pyrrolobenzothiazepinones and pyrrolobenzoxazepinones were investigated as potential anti-AIDS drugs. These compounds were found to inhibit HIV-1 reverse transcriptase (RT) enzyme in vitro and to prevent HIV-1 cytopathogenicity in T4 lymphocytes, without appreciable activity on HIV-2 cytopathic effects, and against HBV as well as calf-thymus DNA alpha-polymerase. Their potency is influenced by substituents at position 6 and on the fused aromatic ring. Specifically, small lipophilic substituents at C-6 were preferred, whereas substitutions on the benzo-fused ring were found to be detrimental to activity, with respect to the unsubstituted compounds. Modification of the pi-system at C-6 is well tolerated, although the replacement of the benzo-fused with a [2,3]naphtho-fused ring leads to a less active compound. Maximum potency and specificity is achieved with a phenyl and an ethyl group at position 6 of the pyrrolobenzoxazepinone system. In the enzymatic assay the oxazepinone derivative (+/-)-6-ethyl-6-phenylpyrrolo[2,1-d][1,5] 16e (IC50 = 0.25 mu M) was found to be more potent than nevirapine (IC50 = 0.5 mu M), tested in the same experimental conditions using rC . dG as a template-primer. In cell culture assay benzoxazepine 16e was active against HIV-1, both wild type and AZT-sensitive, and HIV-1 (IIIB) strains, but not against HIV-2. In enzyme assay although 16e inhibited HIV-1 RT, it was inactive against the nevirapine-resistant recombinant RT Y181C at 50 mu M. Molecular modeling studies suggest that these derivatives present a 3D pharmacophoric arrangement similar to that of other nonnucleoside inhibitors such as nevirapine.

• A Concerted Study Using Binding Measurements, X-ray Structural Data, and Molecular Modeling on the Stereochemical Features Responsible for the Affinity of 6-Arylpyrrolo[2,1-d][1,5]benzothiazepines toward Mitochondrial Benzodiazepine Receptors

  The 7-(acyloxy)-6-arylpyrrolo[2,1-d][1,5]ben derivatives have been recently proposed as a new class of ligands specific for the mitochondrial benzodiazepine receptor (Fiorini et al. J. Med. Chem. 1994, 37, 1427-1438) (Greco et al. J. Med. Chem. 1994, 37, 4100-4108). In this paper we report the X-ray crystallographic structures of three potent (1-3) and two inactive (4 and 5) previously described benzothiazepines, as well as binding affinity constants for two newly assayed analogs in which the acyloxy side chain was replaced by a methoxy group (6) or removed (7). Structure-affinity relationships and molecular mechanics calculations performed using crystal structures as references have led to a revised 3D pharmacophore model accounting for all the data available up until now. Interestingly, the hypothetical receptor-bound conformations of 1-3 display a considerable degree of similarity with their crystal geometries. Additional calculations have confirmed that the poor affinities of benzothiazepines bearing an aroyloxy group (4 and 5) should be ascribed to the steric and/or electronic features of the side chain aryl moieties rather than to unfavorable conformational properties.
