Structure-activity relationships of a series of novel (piperazinylbutyl)thiazolidinone antipsychotic agents related to 3-[4-[4-(6- fluorobenzo[b]thien-3-yl)-1-piperazinyl]butyl]-2,5,5-trimethyl-4- thiazolidinone maleate

HP-236 (3-[4-[4-(6-Fluorobenzo[b]thien-3-yl)-1-piperazinyl]butyl]- 2,5,5-trimethyl-4-thiazolidinone maleate; P-9236) (54) displayed a pharmacological profile indicative of potential atypical antipsychotic activity. A series of piperazinyl butyl thiazolidinones structurally related to this compound were prepared and evaluated in vitro for dopamine D2 and serotonin 5HT2 and 5HT(1A) receptor affinity. The compounds were examined in vivo in animal models of potential antipsychotic activity and screened in models predictive of extrapyramidal side effect (EPS) liability. The synthesis of these compounds, details of their structure-activity relationships, and discovery of a new lead, compound 50, as well as further development of the profiles of compounds 50 and 54 are described.

Kinase domain inhibition of leucine rich repeat kinase 2 (LRRK2) using a [1,2,4]triazolo[4,3-b]pyridazine scaffold

Leucine rich repeat kinase 2 (LRRK2) has been genetically linked to Parkinson’s disease (PD). The most common mutant, G2019S, increases kinase activity, thus LRRK2 kinase inhibitors are potentially useful in the treatment of PD. We herein disclose the structure, potential ligand-protein binding interactions, and pharmacological profiling of potent and highly selective kinase inhibitors based on a triazolopyridazine chemical scaffold.

Discovering protein?ligand chalcogen bonding in the protein data bank using endocyclic sulfur-containing heterocycles as ligand search subsets

The chalcogen bond, the noncovalent, electrostatic attraction between covalently bonded atoms in group 16 and Lewis bases, is present in protein?ligand interactions based on X-ray structures deposited in the Protein Data Bank (PDB). Discovering protein?ligand chalcogen bonding in the PDB employed a strategy that focused on searching the database for protein complexes of five-membered, heterocyclic ligands containing endocyclic sulfur with endo electron-withdrawing groups (isothiazoles; thiazoles; 1,2,3-, 1,2.4-, 1,2,5-, 1,3,4-thiadiazoles) and thiophenes with exo electron-withdrawing groups, e.g., 2-chloro, 2-bromo, 2-amino, 2-alkylthio. Out of 930 ligands investigated, 33 or 3.5% have protein?ligand S—O interactions of which 31 are chalcogen bonds and two appear to be S—HO hydrogen bonds. The bond angles for some of the chalcogen bonds found in the PDB are less than 90, and an electrostatic model is proposed to explain this phenomenon.

High-resolution infrared analysis of seven fundamental bands of gaseous isothiazole between 750 and 1500 cm-1

The gas phase IR spectrum of isothiazole, C3H3NS, between 550 and 1700 cm-1 was recorded with a resolution of ca. 0.003 cm-1. The rotational structure of seven fundamental bands in the region 750-1500 cm-1 has been assigned and analysed by the Watson Hamiltonian model. A number of local resonances in the bands have been identified and explained qualitatively in terms of Coriolis interactions. For each band upper state spectroscopic constants, including band center, rotational constants, and quartic centrifugal distortion constants are given. From observed crossings due to resonances we locate the weak bands nu9(A?) and nu13(A?) at 1041.9(2) and 642.0(3) cm-1, respectively. The anharmonic frequencies have been determined using a cc-pVTZ basis set, at the MP2 and B3LYP levels; the two theoretical methods give very similar results for rotational constants, anharmonic band center frequencies and distortion constants, and many of these are in good agreement with experiment.

Alkaloid extracts from Bitter leaf (Vernonia amygdalina) and Black nightshade (Solanum nigrum) inhibit phosphodiesterase-5, arginase activities and oxidative stress in rats penile tissue

The erectogenic potential of alkaloids extracted from Bitter leaf (Vernonia amygdalina) and Black nightshade (Solanum nigrum) was investigated in this study. Fresh leaves obtained from Bitter leaf and Black night shade were air-dried, pulverized, and extracted for alkaloids. The inhibitory potential of the alkaloid extracts on arginase and phosphodiesterase-5 (PDE-5) activities in rats penile tissue was determined in vitro. The antioxidant properties were also evaluated and the constituent alkaloids quantified using GC-MS. The alkaloid extracts inhibited arginase (0?30.51?mug/ml) and PDE-5 (0?133.69?mug/ml) activities in a concentration-dependent pattern. Similarly, the alkaloid extracts inhibited Fe2+-induced lipid peroxidation in rats penile tissues, scavenged DPPH, OH, and NO radicals as a function of concentration. GC-MS characterization revealed over 20 alkaloid compounds. The inhibition of PDE-5-, arginase-, pro-oxidant-induced lipid peroxidative-, and free radicals-scavenging activities by the alkaloids is suggestive of putative mechanisms underlying their therapeutic use for managing erectile dysfunction in folklore medicine. Practical applications: Alkaloids extracted from Black nightshade (Solanum nigrum) and Bitter leaf (Vernonia amygdalina) were characterized and investigated by standard procedures for inhibitory action against key erectile dysfunction-linked enzymes and antioxidant activity. The alkaloids inhibited erectile dysfunction-linked enzymes (arginase and PDE-5) and showed considerable antioxidant activity in a concentration-dependent manner. In view of this, we suggest the application of these results in the development of erectile dysfunction drugs in the pharmaceutical industry, with probable minimal or no adverse effect.

Estrogen Synthetase Inhibitors. 2. Comparison of the in Vitro Aromatase Inhibitory Activity for a Variety of Nitrogen Heterocycles Substituted with Diarylmethane or Diarylmethanol Groups

The preparation and in vitro aromatase inhibitory activity of a wide variety of heterocyclic (4,4′-dichlorodiphenyl)methanes and -methanols are described.The choice of the two diaryl-bearing moieties as a vehicle for the evaluation of the heterocycles was made by the comparison of series of imidazole and pyridine-derived compunds with similar pyrimidine compounds reported previously.A structural model for the most active compounds is also presented.The activity of a related series of compounds which contain two heterocyclic moieties was found to be consistent with the model.Many of the compounds evaluated, including representatives of the pyridine, imidazole, pyrimidine, pyrazole, triazole, thiazole, and isothiazole classes, exhibit EC50 potencies for aromatase inhibition at low nanomolar levels.These compunds are at least as potent as other nonsteroidal aromatase inhibitors reported previously.
