Abstract:
The present disclosure provides processes for the N-dealkylation of tertiary amines and the use of transition metal catalysts to prepare tertiary N-allyl amine derivatives and secondary amine derivatives thereof. The tertiary amines can be alkaloids and, more particularly, the tertiary amines can be opioids. In specific embodiments, the present disclosure provides methods for use in processes for the synthesis of naloxone and naltrexone from oripavine.
Abstract:
The invention is directed to a method of treating attention-deficit/hyperactivity disorder (ADHD) in a subject, comprising administering a therapeutically effective amount of a carbamoyl compound, or pharmaceutically acceptable salt thereof.
Abstract:
An improved process for the preparation of aryl substituted olefinic amines such as (2S)-(4E)-N-methyl-5-[3-(5-isopropoxypyridin)yl]-4-penten-2-amine and (2S)-(4E)-N- methyl-5-[3-(5-methoxypyridin)yl]-4-penten-2-amine and new intermediates used in said process.
Abstract:
The present invention provides lipids that are advantageously used in lipid particles for the in vivo delivery of therapeutic agents to cells. In particular, the invention provides lipids having the following structure (I) wherein R 1 and R 2 are each independently for each occurrence optionally substituted C 10 -C 30 alkyl, optionally substituted C 10 -C 30 alkenyl, optionally substituted C 10 -C 30 alkynyl, optionally substituted C 10 -C 30 acyl, or -linker-ligand; R 3 is H, optionally substituted C 1 -C 10 alkyl, optionally substituted C 2 -C 10 alkenyl, optionally substituted C 2 -C 10 alkynyl, alkylhetrocycle, alkylphosphate, alkylphosphorothioate, alkylphosphorodithioate, alkylphosphonates, alkylamines, hydroxyalkyls, É-aminoalkyls, É-(substituted)aminoalkyls, É-phosphoalkyls, É-thiophosphoalkyls, optionally substituted polyethylene glycol (PEG, mw 100-40K), optionally substituted mPEG (mw 120-40K), heteroaryl, heterocycle, or linker-ligand; E is O, S, N(Q), C(O), N(Q)C(O), C(O)N(Q), (Q)N(CO)O, O(CO)N(Q), S(O), NS(O)2N(Q), S(O)2, N(Q)S(O)2, SS, O=N, aryl, heteroaryl, cyclic or heterocycle; and, Q is H, alkyl, É-aminoalkyl, É-(substituted)aminoalky, É-phosphoalkyl or É-thiophosphoalkyl.
