(a) Release of CPT from CPT-1a-CPT with or without UV irradiation. (b) Gel permeation chromatographic analysis of CSPT(1a/HCPT) (i) before and (ii) after UV irradiation (365 nm, 40 mW/cm2, 20 min). (c) Release of HCPT and ACPT from CSPT(1a/HCPT) and CSPT(1a/ACPT), respectively, with continuous UV irradiation (+UV) for 15 min or without UV irradiation (−UV). (d) Pulsatile release of HCPT and ACPT from CSPT(1a/HCPT) and CSPT(1a/ACPT), respectively, in response to periodic (every 60 min) UV irradiation for 1 min.
