Compound	MCF-7 log IC50 (μM)	PC-3 log IC50 (μM)
D1	2.12	1.54
37a	1.89	1.67
37b	1.15	1.24
37c	5.01	6.31
37d	5.79	1.81
37e	0.42	0.67
37d	2.30	2.47
37f	4.43	6.11
37g	2.55	2.57
37h	6.28	6.30
37i	−0.21	0.92
Docetaxel (reference drug)	−0.52	−0.52

^aAll the compounds at 100 μM significantly reduced the viability of PC-3 and MCF-7 cells (p < 0.001).⁶⁶
