COX-2 Inhibitors. Celecoxib: Celecoxib is a nonsteroidal antiinflammatory drug (NSAID) that is a COX-2 inhibitor. However, Celecoxib is capable of blocking several other proteins in the COX-2 signaling pathway, and antiapoptotic proteins, such as Bcl-2 and Mcl-1 [67] Synthesis of celecoxib analogs that possess a N-hydroxypyrid-2(1H)one 5-lipoxygenase pharmacophore: biological evaluation as dual inhibitors of cyclooxygenases and 5-lipoxygenase with anti-inflammatory activity.

Celecoxib, a nonsteroidal anti-inflammatory drug (NSAID), is the first specific inhibitor of cyclo-oxygenase-2 (COX-2) approved to treat patients with rheumatism and osteoarthritis In this study we used the scaffold of celecoxib which exhibits several activities against different pathogens, for the design and focused synthesis of a library of 64 compounds. For the primary screen, we used a bioluminescence-based method by constructing a luciferase-expressing reporter M.tb strain which contains the entire bacterial Lux operon cloned in a mycobacterial integrative expression vector

Md Jashim Uddin Faculty of Pharmacy and Pharmaceutical Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2N8 With this aim we have developed a pharmacophore based on the geometric disposition of chemical features in the most favorable conformation of the COX-2 selective inhibitors SC-558 (2; analogue of Celecoxib (1)) and Rofecoxib (3) and the more restrained compounds 4 (DFU) and 5. The pharmacophore model contains a sulfonyl S atom, an aromatic ring (ring plane A) with a fixed position of the normal to the plane, and an additional aromatic ring (ring plane B), both rings forming a dihedral angle. Celecoxib and mefenamic acid, selective COX-2 inhibitors, were used as the standard drugs. Results: The pharmacophore features obtained were aromatic ring (hydrophobicity) and two hydrogen bond.

In the present study we have investigated whether pharmacophore models may account for the activity and selectivity of the known cyclooxygenase-2 (COX-2) selective inhibitors of the phenylsulfonyl tricyclic series, i.e., Celecoxib (1) and Rofecoxib (3), and whether transferring this structural information onto the frame of a nonsteroidal antiinflammatory drug (NSAID), known to.

The pharmacophore generated were based on the diversity of chemical structures of COX-2 inhibitors which were SC-558, celecoxib, 5c-S, SC-75416 and lumiracoxib. As SC-558 was bounded in two different PDB complexes (1CX2 and 6COX), a common pharmacophore feature was generated to represent the pharmacophore feature of SC-553 The studies suggest that the pharmacophore would be useful in the design of molecules with similar or improved activity to that of the celecoxib analogs. In addition, it provides a plausible mechanism of action for the anti-proliferative effects of the benzimidazoles and illustrates that the molecules maintain a similar binding mode to that of.

QSAR methods are widely applied in the drug discovery process, both in the hit‐to‐lead and lead optimization phase, as well as in the drug-approval process. Most QSAR algorithms are limited to using molecules as input and disregard pharmacophores or pharmacophoric features entirely. However, due to the high level of abstraction, pharmacophore representations provide some advantageous. This pharmacophore model contains three chemical features: two aromatic ring, R, (gray) and one hydrogen bond acceptor, HBA, (green). Fig. 3 shows as an example the alignment of the hypothesis model with compound 14 (celecoxib) of the training set. Fig. 2. The top-ranked chemical feature-based pharmacophore model developed usin Figure 4 shows the binding mode of compounds 35, 38, and 39 compared with celecoxib. The p-methyl phenyl group of celecoxib (colored in blue, Fig. 4a-c) resided in a close pocket surrounded by Tyr371 (or Tyr385) and Leu370 (or Leu384) whereas the benzene sulfonamide group (pharmacophore of celecoxib) lied the side pocket of Arg499 (or Arg513)
Crystalline celecoxib was found to contain an ordered network of H‐bonding between all its electron donors (‐S=O group, 2‐N of pyrazole ring and ‐C‐F) and the acceptor (‐N‐H). Amorphous celecoxib retained all these interactions in its disordered molecular arrangement, with a relatively stronger H‐bonding between the interacting.
