A CDK9 inhibitor having short target engagement would enable a reduction of Mcl-1 activity, resulting in apoptosis in cancer cells dependent on Mcl-1 for survival. We report the optimization of a series of amidopyridines (from compound 2), focusing on properties suitable for achieving short target engagement after i.v. administration. By increasing potency and human metabolic clearance, we identified compound 24, a potent and selective CDK9 inhibitor with suitable predicted human pharmacokinetic properties to deliver transient inhibition of CDK9. Furthermore, the solubility of 24 was considered adequate to allow i.v. formulation at the anticipated ED. Short-term treatment with compound 24 led to a rapid dose- and time-dependent decrease of pSer2-RNAP2 and Mcl-1, resulting in cell apoptosis in multiple hematol. cancer cell lines. Intermittent dosing of compound 24 demonstrated efficacy in xenograft models derived from multiple hematol. tumors. Compound 24 is currently in clin. trials for the treatment of hematol. malignancies.

HPLC of Formula: 276684-04-9. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5-(3,4-Dichlorophenyl)-1H-pyrazole-3-carboxylic acid, is researched, Molecular C10H6Cl2N2O2, CAS is 276684-04-9, about Application of a Parallel Synthetic Strategy in the Discovery of Biaryl Acyl Sulfonamides as Efficient and Selective NaV1.7 Inhibitors.

The majority of potent and selective hNaV1.7 inhibitors possess common pharmacophoric features that include a heteroaryl sulfonamide headgroup and a lipophilic aromatic tail group. Recently, reports of similar aromatic tail groups in combination with an acyl sulfonamide headgroup have emerged, with the acyl sulfonamide bestowing levels of selectivity over hNaV1.5 comparable to the heteroaryl sulfonamide. Beginning with com. available carboxylic acids that met selected pharmacophoric requirements in the lipophilic tail, a parallel synthetic approach was applied to rapidly generate the derived acyl sulfonamides. A biaryl acyl sulfonamide hit from this library was elaborated, optimizing for potency and selectivity with attention to physicochem. properties. The resulting novel leads are potent, ligand and lipophilic efficient, and selective over hNaV1.5. Representative lead I demonstrates selectivity over other human NaV isoforms and good pharmacokinetics in rodents. The biaryl acyl sulfonamides reported herein may also offer ADME advantages over known heteroaryl sulfonamide inhibitors.

Synthetic Route of C10H6Cl2N2O2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-(3,4-Dichlorophenyl)-1H-pyrazole-3-carboxylic acid, is researched, Molecular C10H6Cl2N2O2, CAS is 276684-04-9, about Synthesis and anticancer activity of heteroaromatic linked 4β-amido podophyllotoxins as apoptotic inducing agents. Author is Kamal, Ahmed; Tamboli, Jaki R.; Vishnuvardhan, M. V. P. S.; Adil, S. F.; Nayak, V. Lakshma; Ramakrishna, S..

A series of different heteroaromatic linked 4β-amidopodophyllotoxin conjugates were synthesized and evaluated for anticancer activity against five human cancer cell lines. Among the series, one of the compound I showed significant antiproliferative activity in A549 (lung cancer) cell line. Flow cytometric anal. showed that I arrested the cell cycle in the G2/M phase leading to caspase-3 dependent apoptotic cell death. Further, Hoechst 33258 staining and DNA fragmentation assay also suggests that I induces cell death by apoptosis.
