Synthesis of a biphenylalanine analogue of apratoxin a displaying substantially enhanced cytotoxicity

The concise synthesis of the 3,7-dihydroxy-2,5,8,8-tetramethylnonanoic acid moiety of apratoxin A and the total synthesis of compound 3, a 4-biphenylalanine (Bph) analogue of apratoxin A, have been demonstrated. The Bph analogue 3 exhibited a 16-fold increase in cytotoxicity against HCT-116 cells with respect to apratoxin A. This evidence indicated that existing the 4-phenyl group of Bph in 3 significantly enhanced its cytotoxicity, a conclusion corroborated by the 100-fold difference in cytotoxicity against HCT-116 cells observed between apratoxin M7 and apratoxin M16, which is characterized by the presence of a 4-phenyl group where apratoxin M7 displays a 4-methoxy group. Results from a conformational study using a distance geometry method suggested that 3 and apratoxin A adopt similar conformations in CD3CN.

Total synthesis of apratoxin A

We have achieved a total synthesis of apratoxin A in which thiazoline formation was accomplished from the moCys containing amide 4 using PPh 3(O)/Tf2O. Deprotection of the Troc and allyl ester in 17, coupling with tripeptide 3, and d
