초록

7번 위치에 하롤겐이 치환된 여로종류의 퀴놀론 모핵과 시스 또는 트란스-3-아미노-4-메틸오메틸피롤리딘을 반응시켜 7-(시스 또는 트란스-3-아미노-4-메틸티오메틸피롤리디닐) 퀴롤론-3-카르복실산의 신규 항균제를 합성하였다. 새롭게 합성된 퀴놀론의 약효는 그람양성균에 대해 대조물질인 시프로플로삭신보다 매우 탁월하였고, 녹농균이외의 그람음성균에 대해서도 대조물질과 거의 유사하였다. 그리고 임상에서 문제가 되고 있는 메티실린 내성 포도상구균(MRSA)에 대한 신규 퀴놀론의 약효는 더욱더 향상되어진 것으로 나타났다.

New quinolone derivatives of 7-(cis- or trans-3-amino-4-mehtylthiomethylpyrrolidinyl) quinolone-3-carboxylic acids were synthesized by condensation of 7-halo substituted quinolone-3-carboxylic acids with cis- or trans-3-amino-4-mehtylthiomethylpyrrolidine. Some of these compounds showed broad spectra of antibacterial activities against Gram-positive and Gram-negative organisms except Pseudomonas aeruginosa, and exhibited much stronger activity against MRSA.
