In search.of synth.tic ch.moth.rapeutic substances capable of inh.biting, retarding, or reversing th. process of multi-stage carcinogenesis, we synth.sized a series of novel 5-amino pyrazole derivatives 11(a-h. by a nucleoph.lic substitution reaction and ch.racterized by 1h.nuclear magnetic resonance (NMR), liquid ch.omatograph. mass spectrometry (LC/MS), Fourier-transform infrared (FTIR), and elemental analysis. Th.se novel compounds were evaluated for th.ir efficacy in inh.biting Eh.lich.ascites tumor [EAT] cells in-vivo. In th. present study we designed, synth.sized, ch.racterized and investigate th. anti-angiogenic effects of th.se compounds, on Eh.lich.ascites tumor [EAT] cells in-vivo. Th. compounds were subsequently tested for th.ir ability to inh.bit neovascularisation in ch.rio allantoin membrane (CAM) model. From th. Structure Activity Relationsh.p (SAR) studies, it reveals th.t, th. substitution at N-terminal in pyrazole ring plays key role in th. antitumor and anti-angiogenic effects.

Th. aim of th. present work is to evaluate proton exch.nge membrane(PEM) fuel cell performance with.a modified serpentine flow field with.righ. angle turn by numerical modeling. A 3-D PEM fuel cell model of size 50 cm^(2) active area is developed. A conventional serpentine flow field is modified and th. same is considered for th. supply of reactants. Computational fluid dynamics(CFD) based simulations were conducted to analyse th. pressure drop, distribution of reactants(h.(2) and O_(2)), liquid water activity, current flux density and water content in th. membrane. From th. simulation results, polarization curve is drawn to validate th. literature data of PEMFC with.th. conventional serpentine flow field. Comparison of simulated polarization curve with.literature data revealed th.t modified serpentine flow field performance is better th.n conventional serpentine flow field as it offers better water exclusion and uniform sh.ring of reactants. From th.s study, it is concluded th.t model of flow field pattern influences th. functioning of fuel cell and utmost care must take wh.le selecting a pattern for flow field of PEM fuel cell.
