A relationship is found between spectral-luminescent and photochemical properties for mono- and disubstituted chalcone derivatives (RCO)-C-1-CH=CHR2 [R-1, R-2 = Ph, 4-FC6H4, 4-BrC6H4, 2-furyl, 2-thienyl, 4-(PhCONH)C6H4, 4-NH2C6H4, 4-Me2NC6H4].
报道了一组1,3,5-三取代吡唑啉的设计,合成和药理活性。已经基于IR,MS,1 H NMR和13 C NMR光谱分析确定了合成化合物的化学结构。体内评估了合成的1,3,5-三取代吡唑啉衍生物的抗炎,镇痛活性,体外评估了COX-1 / 2抑制作用。在测试的化合物中,衍生物4h,6e,7a,7e和9与参考药物塞来昔布相比,具有更强的抗炎和镇痛作用。基于它们在体内研究中比塞来昔布更高的活性,选择了五种化合物4h,6e,7a,7e和9进行体外环氧合酶抑制试验,以测试其对绵羊COX-1 / 2的抑制活性。将化合物7a,7e和9对接到COX-2结合位点的研究表明,其与选择性COX-2抑制剂SC-558的结合方式相似。

There is provided a composition comprising a compound represented by general formula (I), wherein R
l
represents a 5-iodothiophen-2-yl group or the like, and R
2
represents a 4-dimethylaminophenyl group or the like. This composition is useful for diagnosis of an amyloid-related disease such as Alzheimer's disease because the compound has high binding specificity to amyloid β protein, high permeability through the blood-brain barrier, and a property of being rapidly eliminated from sites other than senile plaques in the brain.

In this work, we proposed the synthesis of a series of pyrazoles derivatives with different substituents on the aromatic rings. We aim to evaluate their influence on the reactivity of the compounds in reactions of α,β-unsaturated chalcones and sulfonyl hydrazide catalyzed by iodine. In order to explain their high and low yields, or the impossibility of obtaining some compounds by applied synthetic

chalconyl-incorporated hydrazone derivatives of mefenamic acid was synthesized in order to obtain new compounds with potential analgesic and anti-inflammatory activity having lesser side effects. The structures of all synthesized compounds were confirmed by means of elemental analysis, IR, 1H NMR, 13C NMR and mass spectra. All compounds were evaluated for their analgesic and anti-inflammatory activities by tail-flick
为了获得具有潜在的止痛和消炎活性且副作用较小的新化合物,合成了一系列苯甲酰并入me苯甲酸的衍生物。通过元素分析,IR,1 H NMR,13 C NMR和质谱确认所有合成化合物的结构。分别通过甩尾法和角叉菜胶诱导的大鼠爪水肿试验评估所有化合物的镇痛和抗炎活性。在所有合成的化合物中,化合物(4a)和(4j)表现出最突出的和一致的抗炎活性。在急性致溃疡性研究中,可以得出以下结论:化合物(4a)和(4j)没有致命的胃肠道毒性。
