New nodularins: A general method for structure assignment

A general method has been developed for assigning the structures of nodularin, a potent hepatotoxin, tumor promoter, and protein phosphatase inhibitor, and minor components isolated from a cultured and a bloom sample of the cyanobacterium Nodularia spumigena. It consists of (1) FABMS analysis (determination of molecular weight and molecular formula), (2) 1H NMR spectroscopy on the parent compound and chiral GC analysis of an acid hydrolyzate (identification and stereochemistry of amino acid components), (3) ozonolysis followed by NaBH4 reduction (conversion to a linear peptide), and (4) FABMS/CID/MS analyses of the linear peptide and the parent compound (sequence analysis). The method has been employed in assigning structures to three new nodularins (2-4) and can be applied to other cyclic peptides containing alpha,beta-dehydroamino acid unit(s), especially the related microcystins, cyclic heptapeptide hepatotoxins. Two nodularins, [DMAdda3]nodularin (2) and [(6Z)Adda3]nodularin (3), were obtained from a bloom sample collected from Lake Ellesmere (New Zealand), and [D-Asp1]nodularin (4) was isolated from cultured cells (strain L-575). The LD50s of 2 and 4 were 150 and 75 mug/kg (ip, mice), respectively, but 3 did not show apparent toxicity at 2.0 mg/kg.

Hydroxyethylene sulfones as a new scaffold to address aspartic proteases: Design, synthesis, and structural characterization

Hydroxyethylene sulfones were developed as novel scaffolds against aspartyl proteases. A diastereoselective synthesis has been established to introduce the required side chain decoration with desired stereochemistry. Depending on the substitution of the hydroxyethylene sulfone core, micro- to submicromolar inhibition of HIV-1 protease is achieved for the S-configuration at P 1 and R-configuration at the hydroxy-group-bearing backbone atom. This stereochemical preference is consistent with the S,R configuration of amprenavir. The racemic mixture of the most potent derivative (Ki = 80 nM) was separated by chiral HPLC, revealing the S,R,S-enantiomer to be more active (Ki = 45 nM). Docking studies suggested this isomer as the more active one. The subsequently determined crystal structure with HIV-1 protease, cocrystallized from a racemic mixture, exclusively reveals the S,R,S-enantiomer accommodated to the binding pocket. The transition state mimicking hydroxy group of the inhibitor is centered between both catalytic aspartates, while either its carbonyl or sulfonyl group forms H-bonds to the structurally conserved water mediating interactions between ligand and Ile50NH/Ile50NH? of both flaps. Biological testing of the stereoisomeric hydroxyethylene sulfones against cathepsin D and beta-secretase did not reveal significant inhibition. Most likely, the latter proteases require inverted configuration at the hydroxy group.

Discovery of a potent, selective, and orally bioavailable histamine H 3 receptor antagonist SAR110068 for the treatment of sleep-wake disorders

Previous studies have shown that compound 1 displayed high affinity towards histamine H3 receptor (H3R), (human (h-H3R), Ki = 8.6 nM, rhesus monkey (rh-H3R), Ki = 1.2 nM, and rat (r-H3R), Ki = 16.5 nM), but exhibited high affinity for hERG channel. Herein, we report the discovery of a novel, potent, and highly selective H3R antagonist/inverse agonist 5a(SS) (SAR110068) with acceptable hERG channel selectivity and desirable pharmacological and pharmacokinetic properties through lead optimization sequence. The significant awakening effects of 5a(SS) on sleep-wake cycles studied by using EEG recording in rats during their light phase support its potential therapeutic utility in human sleep-wake disorders.
