摘要:
The present invention relates to pyrazine derivatives such as those represented by Formulas I and II. X1 to X4 of Formulas I and II may be characterized as electron withdrawing groups, while Y1 to Y4 of Formulas I and II may be characterized as electron donating groups. Pyrazine derivatives of the present invention may be utilized in assessing organ (e.g., kidney) function.
摘要:
Disclosed herein is a selective delivery molecule comprising: (a) an acidic sequence (portion A) which is effective to inhibit or prevent the uptake into cells or tissue retention, (b) a molecular transport or retention sequence (portion B), and (c) a linker between portion A and portion B, and (d) at least one cargo moiety.
摘要:
1,3-Dipole-functional compounds (e.g., azide functional compounds) can be reacted with certain alkynes in a cyclization reaction to form heterocyclic compounds. Useful alkynes (e.g., strained, cyclic alkynes) and methods of making such alkynes are also disclosed. The reaction of 1,3-dipole-functional compounds with alkynes can be used for a wide variety of applications including the immobilization of biomolecules on a substrate.
