    Novel Pyrazolopyrimidopyridazinones with Potent and Selective Phosphodiesterase 5 (PDE5) Inhibitory Activity as Potential Agents for Treatment of Erectile Dysfunction
    摘要:
    Pyrazolo[1', 5': 1,6] pyrimido[4,5-d] pyridazin-4(3H)-ones and their analogues, potentially useful for the treatment of erectile dysfunction, were synthesized and evaluated as inhibitors of phosphodiesterase 5 (PDE5). Several compounds showed IC50 values in the low nanomolar range, and in particular, compound 5r, displaying high potency toward PDE5 (IC50 = 8.3 nM) and high selectivity versus PDE6 (240-fold) appeared to be a very promising new lead both in comparison with the potent but not selective sildenafil and in comparison with some analogues previously reported by us. SAR studies in this triheterocyclic scaffold led us to conclude that the best arranged groups are a methyl in position 1, a benzyl in position 3, a phenyl in position 9, and a linear four-carbon chain in position 6.

    multifunctional luminescent material (BC–B) was synthesized, which exhibits aggregation-induced emission (AIE) enhancement property in high water fraction. The AIE shows a significant impact on the intramolecular charge transfer (ICT) process by controlling intramolecular motion. The above result is demonstrated by density functional theory (DFT) calculations and single-crystal X-ray diffraction. To decrease

  • Enzymatic synthesis of vitamin B6 precursor
    作者:Nevena Prlainovic、Dejan Bezbradica、Zorica Knezevic-Jugovic、Dusan Velickovic、Dusan Mijin

    3-Cyano-4-ethoxymethyl-6-methyl-2-pyridone is an important precursor in the synthesis of vitamin B6, obtained in the addition reaction between 2-cyanoacetamide and 1-ethoxy-2,4-pentanedione catalyzed by lipase from Candida rugosa (triacylglycerol ester hydrolases, EC 3.1.1.3). This work shows new experimental data and mathematical modeling of lipase catalyzed synthesis of 3-cyano-4-ethoxymethyl-6-methyl-2-pyridone, starting from 1-ethoxy-2,4-pentanedione and 2-cyanoacetamide. Kinetic measurements were done at 50 oC with enzyme concentration of 1.2 % w/v. Experimental results were fitted with two kinetic models: the ordered bi-ter and ping-pong bi-ter model, and the initial rates of the reaction were found to correlate best with a ping-pong bi-ter mechanism with inhibition by 2-cyanoacetamide. Obtained specificity constants indicated that lipase from C. rugosa had higher affinity towards 1-ethoxy-2,4-pentanedione and less bulky substrates.
