28197305-0	2017	Ca2+ Selective Host Rotaxane Is Highly Toxic Against Prostate Cancer Cells.	Rotaxanes	20-28	carbonic anhydrase 2	Homo sapiens	0-3	
28197305-4	2017	We synthesized a new rotaxane (CEHR2) that contains a benzyl 15-crown-5 ether as a blocking group to efficiently bind Ca2+.	Rotaxanes	21-29	carbonic anhydrase 2	Homo sapiens	118-121	
28197305-6	2017	It also transfers Ca2+ to a greater extent than CEHR1, which is a rotaxane with an 18-crown-6 ether as a blocking group.	Rotaxanes	66-74	carbonic anhydrase 2	Homo sapiens	18-21
