Bucinnazine (AP-237, 1-butyryl-4-cinnamylpiperazine) is an opioid analgesic drug that was widely used in China to treat pain in cancer patients as of 1986. [1] It is one of the most potent compounds among a series of piperazine- amides first synthesized and reported in Japan in the 1970s.
Flunarizine is a selective calcium antagonist with moderate other actions including antihistamine, serotonin receptor blocking and dopamine D 2 blocking activity. Compared to other calcium channel blockers such as dihydropyridine derivatives, verapamil and diltiazem, flunarizine has low affinity to voltage-dependent calcium channels.
The phenylpropanoids are a diverse family of organic compounds that are biosynthesized by plants from the amino acids phenylalanine and tyrosine in the shikimic acid pathway. [1] Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid , which is the central intermediate in ...
Phenylpropiolic acid, C 6 H 5 CCCO 2 H, formed by the action of alcoholic potash on cinnamic acid dibromide, C 6 H 5 CHBrCHBrCO 2 H, crystallizes in long needles or prisms which melt at 136–137 °C.
The ReMarkable Tablet won't, however, be a good replacement for a more conventional tablet like an iPad. It's not meant for the same function an iPad would provide, like surfing the Internet ...
In 2024, Shen and coworkers disclosed further studies on the biosynthesis of enediynes and reported evidence for a diiodinated trienetetrayne ((13Z)-2,13-diiodopentadeca-1,7,13-triene-3,5,9,11-tetrayne) derived from pentadeca-1,3,5,7,9,11,13-heptaene as a common biosynthetic intermediate for the three known families of enediyne natural products ...
Cinnamaldehyde is an organic compound with the formula C 9 H 8 O or C 6 H 6 CH=CHCHO.Occurring naturally as predominantly the trans isomer, it gives cinnamon its flavor and odor. [1] ...
