摘要:The present invention pertains generally to the field of chemical synthesis, and more particularly to methods for the chemical synthesis of a thiosulfonic acid of Formula (1) by a step of periodate mediated oxidative coupling of a thiosulfonic acid of Formula (2) with an aniline of Formula (3), as described herein. The present invention also relates to such methods which incorporate one or more additional (subsequent and/or preceding) steps, for example, to prepare compounds of Formula (5) from compounds of Formula (1); to prepare compounds of Formula (6) from compounds of Formula (5); and to prepare compounds of Formula (2) from compounds of Formula (4), as described herein.

摘要:The present invention pertains generally to the field of chemical synthesis, and more particularly to methods of chemical synthesis which include the step of preparing a substituted 10H-phenothiazine-3,7-diamine compound of Formula (1) by a step of selective alkylation by reductive amination, in which the corresponding unsubstituted diamine of Formula (4) is reacted with aldehyde/ketone, under reductive amination conditions. The present invention also relates to such methods which incorporate additional subsequent and/or preceding steps, for example, to prepare compounds of Formulae (2) and (3) from compounds of Formula (1), and to prepare compounds of Formula (4) from, for example, compounds of Formulae (5), (6), (7), (8), and (9). Compounds of Formula (1), Formula (2), and Formula (3) are useful, for example, in the treatment of diseases of protein aggregation, such as Alzheimer's disease.

摘要:This invention pertains generally to the field of chemical synthesis and purification, and more specifically to methods of synthesizing and purifying certain 3,7 diamino-phenothiazin-5-ium compounds (referred to herein as “diaminophenothiazinium compoundsâ€?) including Methylthioninium Chloride (MTC) (also known as Methylene Blue). In one embodiment, the method comprises the steps of, in order: nitrosylation (NOS); nitrosyl reduction (NR); thiosulfonic acid formation (TSAF); oxidative coupling (OC); Cr(VI) reduction (CR); isolation and purification of zwitterionic intermediate (IAPOZI); ring closure (RC); chloride salt formation (CSF); one of: sulphide treatment (ST); dimethyldithiocarbamate treatment (DT); carbonate treatment (CT); ethylenediaminetetraacetic acid treatment (EDTAT); organic extraction (OE); and recrystallisation (RX). The present invention also pertains to the resulting (high purity) compounds, compositions comprising them (e.g., tablets, capsules), and their use in methods of inactivating pathogens, and methods of medical treatment and diagnosis, etc., for example, for tauopathies, Alzheimer's disease (AD), skin cancer, melanoma, viral diseases, bacterial diseases, or protozoal diseases. Wherein: each of R 1 and R 9 is independently selected from: —H; C 1-4 alkenyl; and halogenated C 1-4 alkyl; each of R 3NA and R 3NB is independently selected from: C 1-4 alkyl; C 2-4 alkenyl; and halogenated C 4-1 alkyl; each of R 7NA and R 7NB is independently selected from: C 1-4 alkyl; C 2-4 alkenyl; and halogenated C 1-4 alkyl; and X is one or more anionic counter ions to achieve electrical neutrality.
