Reference of 1-Methyl-3-(thiophen-2-yl)-1H-pyrazol-5-amine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Methyl-3-(thiophen-2-yl)-1H-pyrazol-5-amine, is researched, Molecular C8H9N3S, CAS is 118430-78-7, about Improving the Use of Ranking in Virtual Screening against HIV-1 Integrase with Triangular Numbers and Including Ligand Profiling with Antitargets. Author is Garcia-Sosa, Alfonso T.; Maran, Uko.

A delicate balance exists between a drug mol.’s toxicity and its activity. Indeed, efficacy, toxicity, and side effect problems are a common cause for the termination of drug candidate compounds and development projects. To address this, an antitarget interaction profile is built and combined with virtual screening and cross docking for new inhibitors of HIV-1 integrase, in order to consider possible off-target interactions as early as possible in a drug or hit discovery program. New ranking techniques using triangular numbers improve ranking information on the compounds and recovery of known inhibitors into the top compounds using different docking programs. This improved ranking arises from using consensus of ranks between docking programs and ligand efficiencies to derive a new rank, instead of using absolute score values, or average of ranks. The triangular number rerank also allowed the objective combination of results from several protein targets or screen conditions and several programs. Triangular number reranking conserves more information than other reranking methods such as average of scores or averages of ranks. In addition, the use of triangular numbers for reranking makes possible the use of thresholds with a justified leeway based on the number of available known inhibitors, so that the majority of the compounds above the threshold in ranks compare to the compounds that have known exptl. determined biol. activity. The battery of anti- or off-targets can be tailored to specific mol. or drug design challenges. In silico filters can thus be deployed in successive stages, for prefiltering, activity profiling, and for further anal. and triaging of libraries of compounds

Computed Properties of C8H9N3S. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1-Methyl-3-(thiophen-2-yl)-1H-pyrazol-5-amine, is researched, Molecular C8H9N3S, CAS is 118430-78-7, about Domino Reaction of Arylglyoxals with Pyrazol-5-amines: Selective Access to Pyrazolo-Fused 1,7-Naphthyridines, 1,3-Diazocanes, and Pyrroles.

New multicomponent domino reactions of arylglyoxals with pyrazol-5-amines have been established, providing selective access to unprecedented pyrazolo-fused 1,7-naphthyridines, 1,3-diazocanes, and pyrroles (up to 52 examples). The unreported dipyrazolo-fused 1,7-naphthyridines were regioselectively synthesized through a special double [3 + 2 + 1] heteroannulation accompanied by direct C-C formation between two electrophilic sites of arylglyoxals [e.g., PhCOCH(OH)2 + 1,3-dimethyl-5-pyrazolamine in presence of TsOH → I (70%)]. The unusual [3 + 3 + 1 + 1] cyclization resulted in 20 examples of novel dipyrazolo-fused 1,3-diazocanes [e.g., PhCOCH(OH)2 + 1-methyl-3-phenyl-5-pyrazolamine in presence of TsOH → II (71%)], whereas pyrrolo[2,3-c]pyrazoles were obtained in good yields by varying arylglyoxals and pyrazol-5-amines in the ratio 1:2 [e.g., PhCOCH(OH)2 + 1-phenyl-3-methyl-5-pyrazolamine in presence of TsOH → III (78%)]. Mechanisms of formation of these three new types of heterocycles are also proposed.
