2-Benzylsulfanyl-3-(2,2,2-trifluoroethoxy)pyridine

Benzyl 2-(benzylsulfanyl)benzoate

In the title compound, C(21)H(18)O(2)S, the central aromatic ring makes dihedral angles of 5.86 (12) and 72.02 (6)° with the rings of the terminal O-benzyl and S-benzyl groups, respectively. The dihedral angle between the peripheral phenyl rings is 66.16 (6)°. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers. These dimers are linked via C-H⋯π inte...

Elhai et al.’s [1] study evaluates the frequency of radiological cervical spine involvement in young adults with polyarticular JIA (pJIA) compared with RA patients. The authors show that about two-thirds of patients in both groups had radiographic abnormalities in the cervical spine, including anterior atlantoaxial subluxation, erosion of the odontoid process, C1 C2 arthritis and apophyseal joi...

Clearly, the prevention and management of unintended pregnancy are primary health services needed by the majority of women of reproductive age, as well as many comparable men. The training that family physicians receive in family planning and first-trimester abortion is critical, yet few studies have investigated these aspects of their education. The Council on Residency Education in Family Pra...

RNA interference (RNAi) is the process of sequence-specific post-transcriptional gene silencing triggered by double-stranded RNAs1–3. In attempts to identify RNAi triggers that effectively function at lower concentrations, we found that synthetic RNA duplexes 25–30 nucleotides in length can be up to 100-fold more potent than corresponding conventional 21-mer small interfering RNAs (siRNAs). Som...
