In the context of disrupted circadian rhythms, the use of naturalistic lighting optimizes light exposure similar to solar time, allowing for resynchronization of the internal biological clock to the natural light dark cycle (West et al., 2019)

Both have shown efficacy in different models, and the choice depends on the specific research question

R 3 is H, C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, optionally substituted C 3 -C 6 cycloalkyl, optionally substituted C 2 -C 7 heterocycloalkyl, optionally substituted C 6 -C 10 aryl, optionally substituted C 3 -C 9 heteroaryl, OR 6 , NR 5 R 6 , C(O)R 7 , -0O 2 R 6 , C(O)NR 5 R 6 , N(R 5 )C(O)R 7 , N(R 5 )CO 2 R 7 , NHS(O) 2 R 7 , S(O) 2 NR 5 R 6 , or R 2 and R 3 together form an optionally substituted C 2 -C 7 heterocycloalkyl ring

Preclinical studies demonstrate biologic activity relevant to tissue repair, supporting biologic plausibility but not clinical effectiveness

But half-life and duration of effect are different things
