The title compound, C(18)H(15)ClN(2)O(2), is a potential human immunodeficiency virus type-1 (HIV-1) non-nucleoside reverse transcriptase inhibitor. The pyrrolidine ring adopts an envelope and the diazepine ring a boat conformation. In the crystal structure, two isomers (R and S) form centrosymmetric dimers via N-H⋯O hydrogen bonds.

the objective of the current study was to evaluate the reproducibility of a reverse transcriptase pcr (rt-pcr)-based technique to differentiate viable and dead salmonella cells in raw and sterilized milk. the microorganism was initially inoculated into the milk samples followed by incubating at 37°c for 4 h prior to inactivation by heat at 80°c for 10 min. the treated and non-treated samples we...

The non-nucleoside reverse transcriptase inhibitor nevirapine displays in its room temperature (1)H-NMR spectrum signals characteristic of a chiral compound. Following suggestions in the recent literature that nevirapine may display atropisomerism-and therefore be a chiral compound, due to slow interconversion between two enantiomeric conformers-we report the results of an NMR and computational...

Efavirenz is a non-nucleoside reverse transcriptase inhibitor used in combination with other drugs for the treatment of patients with HIV infection. Efavirenz has been reported to cause a positive urine cannabis test reaction which may create problems between HIV-infected patients on Efavirenz and law enforcement agencies. Doctors are at loss whether to issue documents certifying the potential ...

In the title compound, C(18)H(17)BrN(2)O(2), which is a potential -human immunodeficiency virus type 1 (HIV-1) non-nucleoside reverse transcriptase inhibitor, the pyrrolidine ring exhibits an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds [N⋯O = 2.861 (3) Å] link the mol-ecules into centrosymmetric dimers.

objective: common variable immunodeficiency (cvid) is one of the most frequent cases of primary immunodeficiency. it is likely that this heterogeneous disease is caused by several distinct genetic disorders. the activation-induced cytidine deaminase (aid) enzyme is involved in class switching, somatic hypermutation (shm) and processes associated with gene conversion in the germinal center. in o...
