the glass transition temperature of several pvac(1)-b-poly(ma-co-mma) (2) terpolymers with different fractions of methyl acrylate (ma) and methyl methacrylate (mma) repeating units in random copolymer (block 2) were calculated with barton, kwei and topological equations. the calculation was on the basis of the correlation between the fraction of repeating units in random copolymers and theoreti...

aim :  to evaluate the association of dnmt1 and mgmt amino acid substitution polymorphisms and colorectal cancer in iranian population. background : the mgmt and dnmt1 are two important methyltransferase enzymes. amino acid substitution polymorphisms in mgmt and dnmt1 genes may be associated with the genetic susceptibility to sporadic colorectal cancer. patients and methods : we assessed eight ...

Methyl 9-(1-methyl-1H-indol-3-yl)-9-oxononanoate was synthesized using Friedel–Crafts acylation between N-methyl indole and methyl 9-chloro-9-oxononanoate. The structure of the newly compound elucidated 1H-NMR, 13C-NMR, NOESY-1D, ESI-MS, FT-IR, UV-Vis spectroscopy.

The title compound, C8H10N2S, was prepared by reaction of methyl-amine solution, KOH and phenyl-iso-thio-cyanate in ethanol. It adopts a syn-Me and anti-Ph conformation relative to the C=S double bond. The dihedral angle between the N-C(=S)-N thio-urea and phenyl planes is 67.83 (6)°. In the crystal, the mol-ecules centrosymmetrical dimers by pairs of N(Ph)-H⋯S hydrogen bonds. The dimers are li...
