  四唑衍生物作为蛋白精氨酸甲基转移酶I（PRMT I）抑制剂的发展。

  摘要：

  蛋白质精氨酸甲基转移酶1（PRMT1）可以通过将甲基从S-腺苷-L-蛋氨酸（SAM）转移到蛋白质精氨酸的胍基氮原子来催化蛋白质精氨酸甲基化，这会影响多种生物学过程。PRMT1的失调涉及多种疾病，包括癌症。因此，迫切需要开发新型有效的PRMT1抑制剂。在当前的手稿中，通过靶向PRMT1上的底物精氨酸结合位点，设计和合成了一系列1-取代的1H-四唑衍生物，并且有5种化合物表现出对PRMT1的显着抑制作用。最有效的PRMT1抑制剂化合物9a对SAM或底物精氨酸呈非竞争性模式，与PRMT5（属于II型PRMT家族）相比，对PRMT1具有较强的选择性。观察到化合物9a抑制了PRMT1的功能和该途径中的相关因子，并下调了经典的Wnt /β-catenin信号传导途径。通过使用分子动力学模拟和结合自由能计算，仔细分析了化合物9a与PRMT1的结合。这些研究表明9a是有效的PRMT1抑制剂，可以用作进一步

• Oxanilic acids, a new series of orally active antiallergic agents

  antiallergic activity using the rat passive cutaneous anaphylaxis (PCA) test. Many of the oxanilic acid esters are active orally, with the most active species having an aryl 2'-carbamoyl group and a 3'-methoxy group. Hydrolysis of the ester from the oxanilic ester moiety causes a loss of oral activity.

  A new method for the preparation of methoxyisatins from the corresponding methoxyanilines is described. The resulting methoxyisatins were used in the syntheses of several methoxytryptanthrin compounds. The natural product ophiuroidine (4,8,9-trihydroxytryptanthrin) was obtained from the appropriate trimethoxy precursor using a microwave-mediated Prey demethylation.

• Chemical Hybridizing Agents for Chickpea (<i>Cicer arietinum</i> L.):  Leads from QSAR Analysis of Ethyl Oxanilates and Pyridones

  In the self-pollinated crops such as chickpea, induction of male sterility by deployment of chemical hybridizing agents (CHAs) facilitating "two-line" approach holds immense potential in heterosis breeding. A total of 40 test CHAs comprising 20 ethyl oxanilates and 20 pyridones were screened as potential CHAs on chickpea (variety BG 1088) at 500, 800, and 1000 ppm. Three test compounds mostly having either F (4)/Br (5)/CF3 (19) at the para position of the aryl ring from a pool of 20 ethyl oxanilates were identified as the most potent CHAs causing >= 99% induction of pollen sterility and > 90% total flower sterility at 1000-ppm test concentration. Among pyridone derivatives, N-(4-chlorophenyl)-5-carbethoxy-4,6-dimethyl, 1, 2-dihydropyrid-2-one (26) was found to be the most active. Quantitative structure activity relationship (QSAR) analysis has revealed a direct involvement of Swain-Lupton field constant, F, with the target bioactivity which implied that field rather than resonance effect (R) had a positive effect on the activity. The real guiding principle for selectivity was found out to be the hydrophobic parameter pi value. The QSAR models indicated that increased steric bulk at the 4-position on the phenyl ring is associated with enhanced activity. The CHAs appeared to act by mimicking UDP-glucose, the key substrate in the synthesis of callose, or lead to an imbalance in acid-base equilibrium in pollen mother cells resulting in dissolution of callose wall by premature callase secretion.

  Chemical hybridizing agents (CHAs) can facilitate two-line breeding in heterosis programs of crops. Twenty-seven oxanilates having different aromatic substitutions were synthesized and screened as CHAs on two genotypes of wheat, PBW 343 and HID 2733, during two Rabi (winter) seasons, 200001 and 2001-02. The oxanilates prepared by thermal condensation of anilines with diethyl oxalate or by acylation with ethoxycarbonyl methanoyl chloride were sprayed at 1000 and 1500 ppm at the premeiotic stage of wheat, when the length of the emerging spike of the first node was 7-8 mm. Pollen sterility and spikelet sterility were measured in each treatment. Ethyl oxanilates 5, 6, and 25, containing 4-F, 4-Br, and 4-CF3 aromatic substituents, respectively, induced greater than 98% spikelet sterility, the desired level, at 1500 ppm. Quantitative structure -activity relationship analysis revealed a direct relationship between F-p and molecular mass but an inverse relationship between MR, E-S, and R in influencing the bioactivity. Several F-1 hybrids were developed using 5, and at least one showed heterosis.
