Eldecalcitol (1α,25-dihydroxy-2β-(3-hydroxypropoxy)vitamin D3, [developing code: ED-71]), a new osteoporosis treatment drug that was recently approved in Japan, is a best-in-class drug in the class of calcitriol (1α,25-dihydroxyvitamin D3) and its prodrug alfacalcidol (1α-hydroxyvitamin D3), which have been used to treat osteoporosis for 30 years. In a(More)
1alpha,25-Dihydroxy-2beta-(3-hydroxypropoxy)vitamin D(3) (ED-71), an analog of active vitamin D(3), 1alpha,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] is under phase III clinical trials in Japan for the treatment of osteoporosis and bone fracture prevention. Since ED-71 has a substituent at the 2beta-position of the A-ring, it is recognized that the(More)
Eldecalcitol shows higher binding affinity for vitamin D-binding protein (DBP), tighter binding to vitamin D receptor (VDR), and resistance to metabolic degradation via 24-hydroxylation. In silico analysis of the mode of binding demonstrated that the 3-hydroxypropyloxy (3-HP) group of eldecalcitol offers additional hydrogen bond and CH-π interaction for the(More)
OBJECTIVE The decision to use in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), or split insemination (IVF-ICSI) in the first cycle is based on the number of motile sperm. Hence, total fertilization failure (TFF) often occurs during IVF cycles, despite normozoospermia. To investigate whether the cumulative motile swim-up spermatozoa(More)
Eldecalcitol [1alpha,25-dihydroxy-2beta-(3-hydroxypropoxy)vitamin D3, developing code: ED-71] is an analog of active vitamin D3, 1alpha,25-dihydroxyvitamin D3 [1,25(OH)2D3] that possesses a hydroxypropoxy substituent at the 2beta-position of 1,25(OH)2D3. Eldecalcitol has potent biological effects on bone and is now in preparation for approval as a promising(More)
The scaling property of level statistics in the quantum Hall regime, i.e. 2D disordered electron systems subject to strong magnetic fields, is analyzed numerically in the light of the random matrix theory. The energy dependences of the effective level repulsion parameter, the two level correlation, the GUE-GOE crossover parameter, and the rigidity (or ∆(More)
