Cyclo-oxygenase is expressed in cells in two distinct isoforms. Cyclo-oxygenase-1 is present constitutively whilst cyclo-oxygenase-2 is expressed primarily after inflammatory insult. The activity of cyclo-oxygenase-1 and -2 results in the production of a variety of potent biological mediators (the prostaglandins) that regulate homeostatic and disease processes. Inhibitors of cyclo-oxygenase inc...
The crystal structure of a naturally occurring cyclic tetrapeptide cyclo(Gly-L-Ser-L-Pro-L-Glu) [cyclo(GSPE)] was obtained. The conformation of synthesized cyclo(GSPE) fixes the coordination to lead ion in a 1:1 ratio. This cyclo(GSPE)-Pb complex was constructed as an asymmetric 3D network in the crystalline state. The polymerization of a heavy metal ion with a rigid asymmetric cyclic tetrapept...
The rhabditid entomopathogenic nematode associated Bacillus cereus and the antifungal compounds produced by this bacterium were evaluated for their activity in reducing postharvest decay of peanut kernels caused by Aspergillus species in in vitro and in vivo tests. The results showed that B. cereus had a significant effect on biocontrol effectiveness in in vitro and in vivo conditions. The anti...
Collection of peripheral blood stem cells (PBSCs) for autologous cell transplant (ASCT) requires mobilization from the bone marrow. There is variation in choice; during COVID-19 pandemic BSBMT&CT guidelines recommended using granulocyte-colony stimulating factor (G-CSF) alone to minimize use chemotherapy. We report on impact regimen collection, and whether IMiD-containing induction therapy impa...
In the title compound, C(21)H(26)N(2)O, the dihedral angle between the two aromatic rings is 85.90 (19)°. The propenone-hydrazide unit forms dihedral angles of 21.62 (8) and 72.83 (9)°, respectively, with the terminal and central aromatic rings. The 2-methyl-propyl group is disordered over two sites, with occupancies of 0.533 (13) and 0.467 (13). In crystal structure, mol-ecules are linked into...
A series of ring substituted 3-phenyl-1-(1,4-di-N-oxide quinoxalin-2-yl)-2-propen-1-one derivatives were synthesized and tested for in vitro leishmanicidal activity against amastigotes of Leishmania amazonensis in axenical cultures and murine infected macrophages. Structure-activity relationships demonstrated the importance of a radical methoxy at position R3', R4' and R5'. (2E)-3-(3,4,5-trimet...
