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].
