The synthesis, cardiac fraction III cyclic nucleotide phosphodiesterase (PDE-III) inhibition, and positive inotropic activity of a series of 2(1H)-quinazolinones are reported. A general synthesis of the series involved the cyclization of 2-aminoacetophenones with potassium cyanate in acetic acid. Modifications at the 4-position of the quinazoline nucleus were best achieved by formation of the intermediate

본 발명은 중간엽 줄기세포의 혈관내피세포로의 분화 유도를 위한 몰포린/피페라진기를 함유하는 아마이드 유도체 및 이의 의약적 용도를 제공한다. 상기 아마이드 유도체로 처리된 중간엽 줄기세포는 혈관내피세포로 특이적으로 분화 유도되므로 이를 이용하면 풍선확장술 등에 의한 혈관내피세포 손상과 같은 혈관질환을 효과적으로 치료할 수 있게 된다.
synthesized and their differences in solubility were investigated using four chosen solvent systems. Based on our results, 10-cyclohexyl-7-methyl-20(S)-camptothecin exhibited higher solubilities than 7-methyl-10-morpholino-20(S)-camptothecin in polar aprotic solvents. However, these two camptothecin derivatives did not exhibit apparent differences in solubility between 5% dimethyl sulfoxide (DMSO)/95%

The preparation of bridged benzo[1,5]oxazocines and benzo[1,4]diazepines is demonstrated from simple aniline and aldehyde starting materials. A one-pot condensation/6π electrocyclization is followed by an intramolecular trapping of the 2,3-dihydroquinoline intermediate by nitrogen or oxygen nucleophiles to give bridged seven- and eight-membered products. Using 3-hydroxypyridinecarboxaldehydes results
