  Synthesis antimicrobial and antioxidant studies of new oximes of steroidal chalcones

  摘要：

  A convenient synthesis of oximes of steroidal chalcones (4a-4j) was performed and structural assignment of the products was confirmed on the basis of IR, (HNMR)-H-1, C-13 NMR, MS and analytical data. The synthesized compounds were screened for in vitro antioxidant activity by using DPPH method and in vitro antimicrobial activity against different bacterial and fungal strains by agar diffusion method. The activity of the tested compounds against each microbe varied due to structural differences between them. Presence and position of different substituents on the benzene ring of the chalconyl pendent had a marked effect on the activity of the compounds. From the results it can be inferred that the compounds 4a-j showed significant antioxidant activity and antimicrobial activity against all microbial strains used for testing. (C) 2013 Elsevier Inc.

  Pregnenolone derivatives as potential anticancer agents

  摘要：

  Pregnenolone (1) was used as a template to develop new anticancer compounds. Ring-D modification of 1 resulted in the synthesis of benzylidenes 2-17, pyrazolines 18-76, pyrazoles 85-91, hydrazones 77-84, and oximes 92-107 derivatives. The structure of compound 107 was also deduced through single crystal X-ray diffraction studies. The inclusion of furanyl and pyridyl rings to pregnenolone skeleton increases the cytotoxicity of all compounds significantly. Among benzylidene derivatives, only heterocyclic enone 8 (IC50 = 0.74 mu M/mL against HepG2), and 17 (IC50 = 4.49 mu M/mL against HepG2, IC50 = 5.01 mu M/mL against MDA-MB-230 cancer cell line) exhibited a significant activity. The cytotoxicity data of pyrazoline derivatives 18-76 revealed that only furanyl bearing pyrazolines 40,42-44,48, and 49 exhibited significant activities. While all (O-carboxymethyl) oximes, hydazones, and pyrazoles derivatives of pregnenolone did not show any significant activity against both the cell lines. Thus the furanyl bearing enone 8 (IC50 = 0.74 mu M/mL against HepG2), and its pyrazoline derivative 48 (IC50 = 0.91 mu M/mL against MDA-MB-230 cancer cell lines) were identified as the most active compounds in all derivatives of pregnenolone.
