Table 3. EC50 values of the PCAIs against various cancer cell lines.

Compound 48 h EC50 (μM)
NCI-H1299 A549 MDA-MB-468 MDA-MB-231
NSL-YHJ-2-27 5.3* 2.2* 2.2* 4.4
NSL-YHJ-2-62 >50* >50* >50* >50

The potency of NSL-YHJ-2-27 is apparent in all cell lines, however, the non-polyisoprenylated compound, NSL-YHJ-2-62 did not show any effect on cell viability. *These values have previously been reported as part of a broader study of structure-activity relationships of the PCAIs [52].
