isolated from the sea hare Aplysia kurodai together with the congeners aplyronines B (3) and C (4). The absolute stereostructure of aplyronine A (2) was determined by the instrumental analysis (mainly NMR and MS) and the enantioselectivesynthesis of the fragments obtained from chemical degradation of aplyronine A (2). The structures of aplyronines B (3) and C (4) were also elucidated. Cytotoxicity and

Provided herein are compounds having activity against TTR related conditions, and pharmaceutically accepted salts and solvates thereof. Also provided are methods of using the compounds for inhibiting and preventing TTR aggregation and/or amyloid formation in the peripheral nerves, kidney, cardiac tissue, eye and CNS, and of treating a subject with peripheral TTR amyloidosis.
Chirality sensing of choline derivatives is achieved by a self-assembled, racemic triple anion helicate cage which exhibits induced circular dichroism (ICD) upon encapsulation of a chiral guest. The host–guestinteractions were illustrated by NMR, crystal structure, CD and DFT calculations. The absolute configurations and ee values were determined by ICD.
A method for synthesizing levomethadone hydrochloride including producing (R)-2-(dimethylamino)propan-1-ol by reducing N,N-dimethyl-D-alanine using borax, forming (R)-1-chloro-N,N-dimethylpropane-2-amine hydrochloride by chlorinating the (R)-2-(dimethylamino)propan-1-ol, synthesizing levomethadone nitrile hydrochloride by mixing the (R)-1-chloro-N,N-dimethylpropane-2-amine and diphenylacetonitrile with potassium t-butoxide and producing levomethadone hydrochloride by exposing the levomethadone nitrile hydrochloride to a Grignard reagent.
