Studies demonstrate that small molecule targeting of atypical protein kinase C (aPKC) may provide an effective means to control vascular permeability, prevent edema, and reduce inflammation providing novel and important alternatives to anti-VEGF therapies for certain blinding eye diseases. Based on a literature tricyclic thieno[2,3-d]pyrimidine lead (1), an ATP-competitive inhibitor of the aPKC iota (ι) and aPKC zeta (ζ) isoforms, we have synthesized a small series of compounds in 1–2 steps from a readily available chloro intermediate. A single pyridine congener was also made using 2D NMR to assign regiochemistry. Within the parent pyrimidine series, a range of potencies was observed against aPKCζ whereas the pyridine congener was inactive. Selected compounds were also tested for their effect toward VEGF-induced permeability in BREC cells. The most potent of these (7l) was further assayed against the aPKCι isoform and showed a favorable selectivity profile against a panel of 31 kinases, including kinases from the AGC superfamily, with a focus on PKC isoforms and kinases previously shown to affect permeability. Further testing of 7l in a luciferase assay in HEK293 cells showed an ability to prevent TNF-α induced NFκB activation while not having any effect on cell survival. Intravitreal administration of 7l to the eye yielded a complete reduction in permeability in a test to determine whether the compound could block VEGF- and TNFα-induced permeability across the retinal vasculature in a rat model. The compound in mice displayed good microsomal stability and in plasma moderate exposure (AUC and Cmax), low clearance, a long half-life and high oral bioavailability. With IV dosing, higher levels were observed in the brain and eye relative to plasma, with highest levels in the eye by either IV or PO dosing. With a slow oral absorption profile, 7l accumulates in the eye to maintain a high concentration after dosing with higher levels than in plasma. Compound 7l may represent a class of aPKC inhibitors for further investigation.

Background: One of the successful approaches for rational design of bioactive compounds is the bioisosterism strategy. Thus, the bioisosteric relation of thieno[2,3-d]pyrimidin-4-ones with quinazolines, cytosine and uracil resulted in the generation of co

In the present study, some new 2-(pyridin-2-yl)thieno[2,3-d]pyrimidin-4(3H) -ones derivatives (IIa-o) were synthesized. The target compounds (IIa-o) were synthesized through the acid catalyzed condensation of 2-cyano, 3-cyano, and 4-cyano-pyridines with various 2-amino-3-carbethoxythiophenes (Ia-e). All thiophene derivatives were synthesized by Gewald reaction. The structures of the newly synthesized compounds were confirmed by UV-Visible, FT-IR, 1H-NMR, and mass spectral studies. All synthesized compounds were evaluated for their antimicrobial activity against various gram-positive and gram-negative bacterial and fungal strains. Amongst the synthesized compounds IIa, IIb, IId, IIe, and IIm were found to be active. TUeBITAK.
