常見問(wèn)題及建議解決方法

問(wèn)題 1:
What is the difference between S2902 and S1378 which seem to have same structure formula according to the product information?

回答:
These two chemicals are the two different chiral forms of Ruxolitinib. S2902 S-Ruxolitinib is the S form and S1378 Ruxolitinib is the D form. One of the carbon atoms in this molecule is asymmetric, making the two molecules mirror images of each other. The biological activities of these two molecules can be very different because of the confirmation differences.

問(wèn)題 2:
How about the half-life of the compound (Ruxolitinib)? How long is the duration of the inhibitory effect on JAK-STAT signaling?

回答:
The half-life of this compound in body is about 2~3 hours according to previous study. Generally, it is longer in vitro culture medium than in vivo. In paper, Ruxolitinib was also used for 24hours. http://www.bloodjournal.org/cgi/pmidlookup?view=long&pmid=24711661.
