The one-pot synthesis reaction of one mole MCl2.nH2O, where M= Co(II), Ni(II), Mn(II) ,with one mole of 1,5-diphenylthiocarbazone (dithizone;H2dz), of 1,1-bis(diphenyl phosphine)ferrocene (dppf) and 1,2-bis(diphenyl phosphine) ethane (dppe) gave colored complexes of; [Co(Hdz)(k2-dppf)]Cl, [Ni(Hdz)(k2-dppf)]Cl, [Ni(Hdz)(k2-dppe)]Cl and [Mn(Hdz)(k2-dppf)]Cl. The synthesized complexes have been identified by using 1HNMR, IR, UV-Vis spectroscopy, micro elemental analysis and molar conductance. All complexes were tested for their anticancer activities on Human breast cancer cell line CAL5. The results showed that [Ni(Hdz)(k2-dppe)]Cl and[Mn(Hdz)(k2-dppf)]Cl have a highest activities than cisplatin in compared to; [Co(Hdz)(k2-dppf)]Cl, [Ni(Hdz)(k2-dppf)]Cl.

A series of novel 5-((9H-carbazol-9-yl)methyl)-N-((substituted phenyl)(piperazin-1-yl)methyl)-1,3,4-oxadiazol-2-amine (4a-4o) derivatives was synthesized by starting with carbazole which on reaction with ethyl choloroacetate yielded ethyl 2-(9H-carbazole-9-yl)acetate (1), compound (1) on reaction with semicarbazide followed by cyclisation with sulphuric acid gave 5-((9H-carbazole-9-yl)-1,3,4-oxadiazol-2-amine (3) which through Mannich reaction with piperazine and a variety of aromatic aldehydes in the presence of acetic acid yielded the titled compounds (4a-4o). The structures of compounds were characterized by UV, FT-IR, 1H-NMR, MS spectral studies and elemental analysis. All the derivatives were evaluated for their antibacterial, antifungal and anticancer activities. Among the tested compounds 4a, 4d, 4e and 4n exhibited significant antibacterial and antifungal activity while the compounds 4a, 4d, 4k and 4n were found to be active on Human Breast Cancer Cell Line i.e. MCF7.

ABSTRACT We have examined the direct effects of progestins, oestrogens, peptide hormones and growth factors on oestradiol-17β dehydrogenase (OE2DH) activity of cultures of the human breast cancer cell line MCF-7. Cells were cultured in the presence of steroid or peptide for 6 days, after which the number of cells was determined and cellular OE2DH activity assessed. Progesterone, 6α-methyl-17α-hydroxyprogesterone acetate, norethisterone and d(−)-norgestrel all profoundly inhibited cell mitosis and stimulated reductive (oestrone→oestradiol-17β) and oxidative (oestradiol-17β→oestrone) OE2DH activity. Both oestrone and oestradiol-17β directly stimulated reductive OE2DH activity, but had no effect on the oxidative direction. Oestradiol-17β stimulated cell growth only in phenolred free culture medium. Ovine prolactin, LH, epidermal growth factor and transforming growth factor did not alter OE2DH activity but small stimulatory effects on the growth of MCF-7 cells were exerted by prolactin and a combination of transforming growth factor with epidermal growth factor. It is concluded that these results may explain, at least in part, the alterations in mitotic activity and tissue oestradiol-17β levels observed in breast tissue during varying physiological and pathological conditions, such as during the menstrual cycle and in breast cancers.
