The myth of oral hygiene using synthetic mouthwash products.

The synthetic oral cleansing and teeth whitening products like mouthwashes exert adverse effects on teeth, gums and mucous membrane of oral cavity and their extensive use is being criticized. Determining the effect of frequent use of mouthwashes, human cheek cells and their DNA have been studied. Five mouthwash brands were tested and their effects were examined on membrane and DNA of human cheek cells which were found to be very expressive and severe.

Anticancer activity of Cinnamon tamala leaf constituents towards human ovarian cancer cells.

Bioassay guided fractionation of Cinnamon tamala leaf extracts yielded bornyl acetate (1), caryophylene oxide (2), p-coumaric acid (3) and vanillic acid (4) using A-2780 human ovarian cancer cell lines. The structures of the isolated compounds were confirmed through spectroscopic techniques (EIMS, (1)H and (13)C NMR). Compound 1 exhibited highest cytotoxicity with 90.

(5Z)-5-(2-Hy-droxy-benzyl-idene)-3-(4-methyl-phen-yl)-2-sulfanyl-idene-1,3-thia-zolidin-4-one.

In the title compound, C(17)H(13)NO(2)S(2), the dihedral angles between the 2-sulfanyl-idene-1,3-thia-zolidin-4-one group and the pendant toluene and 2-hy-droxy-benzene rings are 74.62 (6) and 8.73 (12)°, respectively.

Cyclo-hexa-naminium trichloro-acetate.

In the crystal of the title compound, C(6)H(14)N(+)·C(2)Cl(3)O(2) (-), centrosymmetric assemblies of two cyclo-hexa-naminium cations and two trichloro-acetate ions are linked by N-H⋯O hydrogen bonds, thereby forming R(4) (4)(12) ring motifs. Further N-H⋯O inter-actions link the tetra-mers into chains propagating along the a axis.
