Tertiary Amine Pyrazolones and Their Salts as Inhibitors of Mutant Superoxide Dismutase 1-Dependent Protein Aggregation for the Treatment of Amyotrophic Lateral Sclerosis
摘要:
Pyrazolone derivatives have previously been found to be inhibitors of Cu/Zn superoxide dismutase 1 (S OD 1) - dep en dent protein aggregation, which extended survival of an amyotrophic lateral sclerosis (ALS) mouse model. On the basis of ADME analysis, we describe herein a new series of tertiary amine-containing pyrazolones and their structure activity relationships. Further conversion to the conjugate salts greatly improved their solubility. Phosphate compound 17 exhibited numerous benefits both to cellular activity and to CNS-related drug-like properties in vitro and in vivo, including microsomal stability, tolerated toxicity, and blood brain barrier permeation. These results indicate that tertiary amine pyrazolones comprise a valuable class of ALS drug candidates.
Benzylamines: synthesis and evaluation of antimycobacterial properties
摘要:
The synthesis of benzylamines with various N-alkyl chains and substituents in the aromatic system as well as their evaluation on Mycobacterium tuberculosis H 37 Ra are described. The most active compounds in this test, N-methyl-3-chlorobenzylamine (19, MIC 10.2 micrograms/mL), N-methyl-3,5-dichlorobenzylamine (93, MIC 10.2 micrograms/mL), and N-butyl-3,5-difluorobenzylamine (103, MIC 6.4 micrograms/mL), also exhibited a marked inhibitory effect on Mycobacterium marinum and Mycobacterium lufu used for the determination of antileprotic properties. The combinations of 93 with aminosalicylic acid, streptomycin, or dapsone exert marked supra-additive effects on M. tuberculosis H 37 Ra.
