In response to adenosine 5'-diphosphate, the P2Y1 receptor (P2Y1R) facilitates platelet aggregation, and thus serves as an important antithrombotic drug target. Here we report the crystal structures of the human P2Y1R in complex with a nucleotide antagonist MRS2500 at 2.7 Å resolution, and with a non-nucleotide antagonist BPTU at 2.2 Å resolution. The(More)
Purine (N)-methanocarba-5'-N-alkyluronamidoriboside A3 adenosine receptor (A3AR) agonists lacking an exocyclic amine resulted from an unexpected reaction during a Sonogashira coupling and subsequent aminolysis. Because the initial C6-Me and C6-styryl derivatives had unexpectedly high A3AR affinity, other rigid nucleoside analogues lacking an exocyclic amine(More)
The need to achieve realism in theatrical motion pictures with miniature models requires precise positioning, close tolerances, and a high degree of repeatability. A particular movement of the camera and the subject(s) may be repeated several times to create mattes or other special effects involving multiple exposures. Traditionally, miniatures photography(More)
