AbstractA library comprises diversely substituted novel 3,4′-bicarbostyril derivatives have been designed by molecular hybridization technique and synthesized via multi-component reaction . Compounds G22 (MIC = 12.5 µg/mL) and G38 (MIC = 25 µg/mL) exhibited 99% inhibition against Mycobacterium tuberculosis, while compounds G40 (IC50 = 0.019 µg/mL) and G20 (IC50 = 0.028 µg/mL) found to have excellent

A new series of N-arylamino biquinoline derivatives 5a–x were synthesized under microwave irradiation technique in good yields compared with conventional method and screened for their antimicrobialactivity. All the synthesized compounds have been established by elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data. In vitro antimicrobialactivity was carried out against three Gram-positive
与常规方法相比,在微波辐射技术下以高收率合成了一系列新的N-芳基氨基联喹啉衍生物5a – x,并对其抗菌活性进行了筛选。通过元素分析,IR,1 H NMR,13 C NMR和质谱数据确定了所有合成的化合物。对三种革兰氏阳性菌(枯草芽孢杆菌,破伤风梭菌,肺炎链球菌),三种革兰氏阴性菌(大肠杆菌,鼠伤寒沙门氏菌,霍乱弧菌)进行了体外抗菌活性)和两种真菌(烟曲霉,白色念珠菌)采用肉汤微量稀释法。在研究的化合物中,化合物5u对肺炎链球菌和伤寒沙门氏菌显示出有希望的抗菌活性。

Die aus monosubstituierten Hydrazinen mit Dimedon erhaltenen Enhydrazine ergaben mitfreiem Amin und wäßriger Formaldehydlösung in keinem Fall faßbare Aminomethylprodukte. Erst die Umsetzung mit Methyleniminiumsalzen in Acetonitril führte zu Salzen der Mannichbasen.
