  • New $\alpha$-pyrones (1 and 2) and cyclohexenones (13 and 14) were isolated along with known analogues (3, 5−12) from the ethyl acetate extract of the whole broth of the fungus Paecilomyces lilacinus, a strain derived from a marine sponge Petrosia sp. Their structures were established by interpretation of 1D and 2D NMR, and FABMS data. It is interesting to isolate cyclohexenone derivatives from the genus Paecilomyces (family Trichocomaceae, order Eurotiales), since these cyclohexenones were previously reported only from far distinct genera, Phoma and Alternaria (family Pleosporaceae, order Pleosporales). Compounds 6, 7, and 9 were evaluated for cytotoxicity against a small panel of human solid tumor cell lines. Their cytotoxicity was insignificant upto a concentration of 30 ${\mu}g/mL$.

  • 살균활성을 보이는 천연물인 incrustoporin(1)의 기본골격인 2(5H)-furanone을 포함하는 유도체 2를 microwave를 이용한 Suzuki-Miyaura coupling 반응으로 합성하였고, 또한 furanone의 화학구조에서 산소원자를 탄소원자로 치환한 2-cycloalkenone 유도체 3 및 4를 유사한 방법으로 합성하였다. 합성한 이들 유도체들의 살균활성을 6종의 식물병원균에 대하여 조사한 결과, 벼 도열병 및 토마토 역병에 대하여 다소 방제효과를 나타내었다. 따라서 이들 유도체들은 다양한 구조변화를 통한 살균제 개발에 활용할 수 있을 것으로 생각된다.
