4122 C-Curarine C-Curarine is a Curare alkaloid that is structurally similar to D-tubocurarine. Curare is a non-depolarizing muscle relaxant that blocks the nicotinic acetylcholine receptor (nAChR), one of the two types of acetylcholine (ACh) receptors, at the neuromuscular junction. The main toxin of curare, D-tubocurarine, occupies the same position on the receptor as ACh with an equal or greater affinity making it a competitive antagonist. 7168-64-1 6391813 C40H44N4O White powder. It has been prpoposed that surarine speeds up destruction of chemical transmitter, and raises the threshold point at which excess of the transmitter is able to exert its depressant power. (A15428) No indication of carcinogenicity to humans (not listed by IARC). The main toxin of curare, D-tubocurarine, occupies the same position on the receptor as ACh with an equal or greater affinity making it a competitive antagonist. 2014-08-29T05:02:02Z 2026-04-06T11:01:11Z C09144 true [H]\C(C)=C1\C[N+]2(C)CCC34C2CC1C1=CN2C5=CC=CC=C5C56CC[N+]7(C)C\C(=C(\[H])C)C(CC57)C5=CN(C7=CC=CC=C37)C41OC265 C40H44N4O InChI=1S/C40H44N4O/c1-5-25-23-43(3)17-15-37-29-11-7-10-14-34(29)42-22-32-28-20-36-38(16-18-44(36,4)24-26(28)6-2)30-12-8-9-13-33(30)41-21-31(27(25)19-35(37)43)39(37,42)45-40(32,38)41/h5-14,21-22,27-28,35-36H,15-20,23-24H2,1-4H3/q+2/b25-5+,26-6+ DWELRYDMYVJVSL-GQBJSJAWSA-N 596.8025 596.35041489 Exogenous Solid 16735754 CHEM003028 NS00121179 15.71 204.19029999999998 68.7530151558532 0 3 0 -4.114069983829551 2 12 2.11 -6.57 1.81e-04 g/l
