Systematic SAR studies of in vitro factor Xa inhibitory activity around N-[(5-chloropyridin-2-yl)-2-(4-N,N-dimethylcarbamimidoyl)benzamido]benzamide were performed by modifying each of the three Ph rings. A class of highly potent, selective, efficacious and orally bioavailable direct factor Xa inhibitors was discovered. These compounds were screened in hERG binding assays to examine the effects of substitution groups on the hERG channel affinity. From the leading compounds, betrixaban (PRT054021) has been selected as the clin. candidate for development.

Archibald, John L. published the artcileDesign of an antithrombotic-antihypertensive agent (Wy 27569). Synthesis and evaluation of a series of 2-heteroaryl substituted dihydropyridines, Recommanded Product: 2-Chloro-3-(trifluoromethyl)benzaldehyde, the main research area is pyridine heteroaryl preparation antithrombotic antihypertensive; antithrombotic antihypertensive heteroaryldihydropyridine.

An approach to the design of potential combined antithrombotic-antihypertensive agents is described. A series of 1,4-dihydropyridines bearing a 1H-imidazol-1-yl or pyrid-3-yl substituted side chain in the 2-position, e.g. I (R, R1 = Me, Et; R2 = 3-pyridyl, 1-imidazolyl, R3 = 2, 3-NO2, X = CH2, CH2O) were synthesized and tested for antihypertensive activity in spontaneously hypertensive rats and for inhibition of TXA2 synthetase in rabbit platelets, in vitro. I (R = Et, R1 = Me, R2 = 1-imidazolyl, R3 = 3-NO2, X = CH2) (II) was shown to be similar in potency to nitrendipine as an antihypertensive agent. II inhibited TXA2 synthetase in rabbit and human platelets in vitro and reduced plasma TXB2 levels in rats at antihypertensive dose levels. The reductions in thromboxane production observed in vivo and in vitro were accompanied by enhanced levels of 6-KPGF1α, reflecting diversion of the arachidonic acid cascade towards prostacyclin synthesis.

Kim, Doyeon published the artcileIdentification and characterization of potent, selective and metabolically stable IKKβ inhibitor, Recommanded Product: 4-(4-Chlorophenoxy)benzaldehyde, the main research area is rhodanine derivative preparation IKKbeta inhibitor structure activity; Allosteric inhibitor; IKKβ inhibitor; NF-κB; Reumatoid arthritis.

The authors have previously reported the identification of a rhodanine compound (I) with well-balanced inhibitory activity against IKKβ and collagen-induced TNFα activated cells. However, the authors need more optimized compounds because of its instability over plasma and microsome. As part of a program directed toward the optimization of IKKβ inhibitor, the authors modified a substituent of parent compound to a series of functional groups. Among substituted compounds, fluorine substituent (II) on the para position of Ph ring restored the stability toward plasma and microsome while retaining inhibitory potency and selectivity against IKKβ over other kinases. Also, the authors have demonstrated that compound (II) is an ATP non-competitive inhibitor and safe enough to apply to animal experiment from an acute toxicity test.

Roy, Kunal published the artcileQSTR with extended topochemical atom (ETA) indices. 14. QSAR modeling of toxicity of aromatic aldehydes to Tetrahymena pyriformis, Recommanded Product: 6-Chloro-2-fluoro-3-methylbenzaldehyde, the main research area is QSTR extended topochem atom index QSAR model acute toxicity; model acute toxicity aromatic aldehyde Tetrahymena.

Quant. structure-toxicity relationship (QSTR) models were developed in this study using Extended Topochem. Atom (ETA) indexes for a large group of 77 aromatic aldehydes for their acute toxicity against the protozoan ciliate Tetrahymena pyriformis. The ETA models have been compared with those developed using various non-ETA topol. indexes. Attempt was also made to include the n-octanol/water partition coefficient (log Ko/w) as an addnl. descriptor considering the importance of hydrophobicity in toxicity prediction. Thirty different models were developed using different chemometric tools. All the models were validated using internal validation and external validation techniques. The statistical quality of the ETA models was comparable to that of the non-ETA models. The ETA models have shown the important effects of steric bulk, lipophilicity, presence of electroneg. atom containing substituents and functionality of the aldehydic O to the toxicity of the aldehydes. The best ETA model (without using log Ko/w) shows encouraging statistical quality (Qint2 =0.709, Qext2 =0.744). It is interesting to note that some of the topol. models reported here are better in statistical quality than previously reported models using quantum chem. descriptors.

Kumar, Praveen published the artcileComputational Study and Synthesis of a New Class of Anticonvulsants with 6 Hz Psychomotor Seizure Test Activity: 2-(1,3-benzodioxol-5-yloxy)- N′-[substituted]-acetohydrazides, Recommanded Product: 4-(4-Chlorophenoxy)benzaldehyde, the main research area is anticonvulsant drug psychomotor seizure test; 2-(1; 3-benzodioxol-5-yloxy)-N’-[substituted]-acetohydrazides; 6 Hz psychomotor seizure test; computational study; docking; neurotoxicity.; synthesis.

About 50 million epileptic cases worldwide and 12 million in India are reported. Currently, available drugs yield adequate control of seizure in 60-70% of patients and show many toxic effects. These actualities provoked the search for novel, more efficacious and safer anticonvulsants. The concatenation of 2-(1,3-benzodioxol-5-yloxy)-N′-[substituted]-acetohydrazides SA 1- 10 was designed by mol. hybridization, optimized by computational study and synthesized with the objective of obtaining a prototype of potent anticonvulsant mols. especially active against partial seizures. Computational study was performed to calculate the pharmacophoric design, projection of the pharmacokinetic parameters and docking scores of the titled compounds with mol. targets of epilepsy. The anticonvulsant activity was ascertained by 6 Hz psychomotor seizure test. Minimal motor impairment showing neurotoxicity was assessed using the Rotarod test. Titled compounds possessed the indispensable elements of pharmacophore and displayed good binding affinity with mol. targets of epilepsy, such as GABA (A) alpha-1 & delta receptor, glutamate receptor, Na+/H+ exchanger and GABA- aminotransferase in docking studies. The most potent compound of the concatenation was 2-(1,3-benzodioxol-5-yloxy)-N′-[4-(4- chlorophenoxy)benzylidene]-acetohydrazide SA 4, showing 100% protection at four different time points with ED50 value 146.8 mg/kg at a TPE of 1 h in mice. The protection shown in 6 Hz test is implicated as the compound′s ability to control partial seizures. Thus, the titled compounds can be considered as potential prototype candidates for antiepileptic therapy against partial seizures.
