- Preparation and pharmacological evaluation of a novel series of 2-(phenylthio)benzo[b]thiophenes as selective MT2 receptor ligands
-
A series of N-(2-(5-fluoro-2-(4-fluorophenylthio)benzo[b]thiophen-3-yl) ethyl)acylamides was synthesized and evaluated for binding affinity and intrinsic activity at melatonin receptors. The affinity of each compound for the melatonin receptors was determined by binding studies on cloned human MT 1 and MT2 receptors expressed in CHO cells. Agonist and antagonist potency was measured on the [35S]GTPγS binding assay for the most interesting compounds. The new derivatives 8-14 showed modest to high selectivity (between 4 and 220) for MT2 receptors. The most selective compound, N-(2-(5-fluoro-2-(4-fluorophenylthio)benzo[b]thiophen-3-yl) ethyl)but-3-enamide (14), an MT2 ligand with affinity for the MT 2 receptor similar to that of melatonin and a 220-fold preference over MT1 receptors, acts as a partial agonist. In addition, N-(2-(5-fluoro-2-(4-fluorophenylthio)benzo[b]thiophen-3-yl)ethyl)propionamide (9), a nanomolar MT2 ligand with a good selectivity ratio (MT 1/MT2 = 51) shows antagonist activity on both melatonin receptors.

- C17,20-lyase inhibitors I. Structure-based de novo design and SAR study of C17,20-lyase inhibitors.
-
Novel nonsteroidal C(17,20)-lyase inhibitors were synthesized using de novo design based on its substrate, 17 alpha-hydroxypregnenolone, and several compounds exhibited potent C(17,20)-lyase inhibition. However, in vivo activities were found to be short-lasting, and in order to improve the duration of action, a series of benzothiophene derivatives were evaluated. As a result, compounds 9h, (S)-9i, and 9k with nanomolar enzyme inhibition (IC(50)=4-9 nM) and 9e (IC(50)=27 nM) were identified to have powerful in vivo efficacy with extended duration of action. The key structural determinants for the in vivo efficacy were demonstrated to be the 5-fluoro group on the benzothiophene ring and the 4-imidazolyl moiety. Superimposition of 9k and 17 alpha-hydroxypregnenolone demonstrated their structural similarity and enabled rationalization of the pharmacological results. In addition, selected compounds were also identified to be potent inhibitors of human enzyme with IC(50) values of 20-30 nM.

- Halogeno-Substituted 2- and 3-Methylbenzothiophenes: Use of 1H NMR Spectral Analysis and 1H Nuclear Overhauser Effect for Locating the Halogen Substituent
-
Thirty-seven halogeno-substituted 2- and 3-methyl-(or halogenomethyl)-benzothiophenes, including 17 new compounds, were prepared.The constitution of 14 of these was confirmed by full analysis (LAOCOON) of their 80 MHz 1H NMR spectra and by 1H NOE measurements.In this way a by-product from the preparation of 4- and 6-bromo-3-bromomethylbenzothiophenes was shown conclusively to be 5-bromo-3-bromomethylbenzothiophene.The 3-substituted benzothiophenes showed greater NOE enhancement factors at H-4 than at H-2 when the 3-methyl or halogenomethyl substituent was irradiated.

- Orally absorbable cephalosporine antibiotics. 1. Structure-activity relationships of benzothienyl- and naphthylglycine derivatives of 7-aminodeacetoxycephalosporanic acid
-
A structure-activity relationship study of a number of orally absorbed cephalosporins together with their syntheses is described. These new cephalosporins are benzothienyl- and naphthylglycine derivatives of 7-aminodeacetoxycephalosporanic acid. Several different synthetic methods for the glycine side chains, their protection, and the final acylations are reported. Several of these analogues were more active than cephalexin both in vitro and r538w2 =(R)-7-(3-Benzothienylglycylamido)-3-methyl-3-cephem-4-carb oxylic in vivo against commonly encountered Gram-positive bacteria. (R)7-(3-Benzothienylglycylamido)-3-methyl-3-cephem-4-carboxylic acid has emerged as a potent antibacterial agent and is currently undergoing preclinical evaluation.

- Addition Reactions of Benzothiophen. Part 1. Self-addition and Addition of Simple Aromatic Hydrocarbons
-
Benzothiophen undergoes facile addition reactions across the 2,3-bond when treated with aluminium chloride in an appropriate solvent at 0 or 20 deg C.In carbon disulphide or dichloromethane, it undergoes self-addition to give two or more of the four possible 2- or 3-(2- or 3-benzothienyl)2,3-dihydrobenzothiophens (3)-(6).In the presence of an aromatic solvent, the dimerization reaction just mentioned predominates at low temperatures (0 deg C or below), or at room temperature if the solvent is benzene, chlorobenzene, t-butylbenzene, isopropylbenzene, or 1,3,5-trimethylbenzene.At room temperature, in toluene, ethylbenzene, and 1,2- or 1,4-dimethylbenzene, solvent addition occurs to give a mixture of the corresponding 2- and 3-aryl-2,3-dihydrobenzenethiophens.At 80 deg C, benzene and toluene give the fully aromatic 2-arylbenzothiophen.The reactions are discussed in terms of an ionic mechanism involving protonation of benzothiophen by moist aluminium chloride and reaction of the resulting electrophile with benzothiophen or with an aromatic substrate.
