Kata Kunci:
sitotoksitas, UK-3A, sel P388, ester 3-hidroksipikolinil dioktil glutamatAbstrak
Antibiotika UK 3A telah diisolasi sebagai komponen minor dari Streptomyces Sp. 517-02. Senyawa ini dielusidasi sebagai turunan dilakton yang memiliki 9 cincin. Senyawa analog UK-3A, yaitu ester 3-hidroksipikolinil dioktil glutamat disintesis dari L-glutamat dan oktanol, kemudian hasil nya direaksikan dengan 3-hidroksipikolinat. Produk akhir tersebut diidentifikasi dengan menggunakan 1H dan 13C FT-NMR, spektrofotometri FT IR dan LC-MS. Uji bioassay menunjukkan bahwa senyawa ester 3-hidroksipikolinil dioktil glutamat menunjukkan aktivitas menghambat pertumbuhan sel kanker leukemia P388 dengan nilai IC50 9.80 µg/mL, lebih tinggi dari aktivitas hambatan UK 3A dengan nilai IC50 38.4 µg/mL.
