In the crystal structure of the title compound, C(28)H(21)Cl(2)N, π-π inter-actions link pairs of mol-ecules into centrosymmetric dimers with a distance of 3.756 (3) Å between the centroids of the pyridine rings. Weak inter-molecular C-H⋯Cl hydrogen bonds further link these dimers into chains propagating along [01]. The pyridine ring forms dihedral angles of 21.52 (1) and 55.87 (2)°, respective...

Background: In cancers of prostate, breast, oropharynx, lung, hypopharynx and skin, human tissue kallikreins has been demonstrated as a main role in these problems. There are many research works in which some human tissue kallikreins are expressed in salivary glands. In the present study, the main goal was to determine expression of human tissue kallikreins 4, 8, 10, 11 and 13 ...
