2H-Pyrrolo[3,4-b] [1,5]benzothiazepine derivatives as potential inhibitors of HIV-1 reverse transcriptase was written by Di Santo, Roberto;Costi, Roberta. And the article was included in Farmaco in 2005.Computed Properties of C7H5ClF2 This article mentions the following:
A number of 2H-pyrrolo[3,4-b] [1,5]benzothiazepine derivatives (PBTAs) 7-25 and the related synthetic intermediates 3-pyrrolyl aryl sulfones (PASs) 26-32 were designed, synthesized and tested as potential anti-HIV-1 agents targeted at the reverse transcriptase (RT). The PBTAs were conceived as tricyclic analogs of nevirapine, pyrrolo[1,2-b] [1,2,5]benzothiadiazepine 5 (PBTD) and pyrrolo[2,1-d] [1,2,5]benzothiadiazepine 6, NNRTIs endowed with potent anti-HIV-1 activities. The majority of tested PBTAs were active against HIV-1-induced cytopathicity in MT-4 cells at concentrations ranging from 0.3 to 40 μM. In particular, compound 10 was the most potent derivative with EC50 = 0.3 μM, comparable to that of nevirapine used as reference drug. In the 3-pyrrolyl aryl sulfones (26-32) series only three sulfones were found active against HIV-1 replication cycle. The following preliminary SAR could be depicted for the title derivatives:(i) the conformationally restrained PBTAs are more potent than the corresponding open counterparts (PASs); (ii) the DMA group give the highest anti-HIV-1 potency in the PBTAs series; (iii) PBTAs and the corresponding thiones are equipotent; (iv) an unsubstituted amino group, as part of p-chloroanilino moiety, is a strong determinant for the antiviral activity in the PASs series. The most potent derivatives in cell-based assays were proven to target the RT in enzyme assays. Unfortunately, none of the test compounds inhibited the multiplication of clin. relevant drug-resistant viruses (mutants of HIV-1 carrying K103N and Y181C mutations) at concentrations lower than 30 μM. However, the good results obtained against replication of wt HIV-1, lead us to consider compound 10 as a lead compound for further investigation in this field. In particular, our efforts will be directed to modifications of 10 devoted to obtain new derivatives active against HIV-1 mutant strains. In the experiment, the researchers used many compounds, for example, 2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4Computed Properties of C7H5ClF2).
2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Computed Properties of C7H5ClF2
