A series of salicylic acid analogues of celecoxib where the phenylsulfonamide moiety in the structure of celecoxib is replaced by salicylic acid moiety was synthesized and tested for in vitro cyclooxygenase (COX)-1 and COX-2 enzyme inhibition. Among the series, 5-substituted-2-hydroxy-benzoic acid analogues (7a–7h) generally showed better inhibitory activities on both enzymes than 4-substituted-2-hydroxy-ben-zoic acid analogues (12a–12h). In particular, the chloro analogue 7f which had the highest inhibitory effect (IC50=0.0057μM) to COX-1 with excellent COX-1 selectivity (SI=768) can be classified as a new potent and selective COX-1 inhibitor. The high inhibitory potency of 7f was rationalized through the docking simulation of this analogue in the active site of COX-1 enzyme.

The emergence of hydrogen sulfide (H2S) as an important signalling molecule in redox biology with therapeutic potential has triggered interest in generating this molecule within cells. One strategy that has been proposed is to use carbonyl sulfide (COS) as a surrogate for hydrogen sulfide. Small molecules that generate COS have been shown to produce hydrogen sulfide in the presence of carbonic anhydrase, a widely prevalent enzyme. However, other studies have indicated that COS may have biological effects which are distinct from H2S. Thus, it would be useful to develop tools to compare (and contrast) effects of COS and H2S. Here we report enzyme-activated COS donors that are capable of inducing protein persulfidation, which is symptomatic of generation of hydrogen sulfide. The COS donors are also capable of mitigating stress induced by elevated reactive oxygen species. Together, our data suggests that the effects of COS parallel that of hydrogen sulfide, laying the foundation for further development of these donors as possible therapeutic agents.

Paragraph 0059-0063, (2018/03/28)
The invention discloses a 4-substituted pyridine-2-formamide compound, a preparation method thereof and an application. The 4-substituted pyridine-2-formamide compound has a structure as shown in a formula I, and the chemical name of the compound is 4-{4-[3-(4-chlorine-3-trifluoromethyl-phenyl)-ureide]-3-carboxyl phenoxy}-N-picoline-2-carboxylic methylamine. According to the preparation method of the 4-substituted pyridine-2-formamide compound, 4-chlorine-2-picolinic acid serves as an initial raw material, and the compound in the formula I is prepared by acylating chlorination, amination, substitution reaction and condensation reaction. The 4-substituted pyridine-2-formamide compound retains a Sorafenib efficacy structure, 5-aminosalicylic acid or aminosalicylic acid ester achieving a positive pharmacological function in the metabolic process replaces p-aminophenol with large toxic and side effects, efficacy can be improved, and the toxic and side effects are reduced.

Calcium coordination solids were synthesized and evaluated for delivery of olsalazine (H4olz), an anti-inflammatory compound used for treatment of ulcerative colitis. The materials include one-dimensional Ca(H2olz)?4 H2O chains, two-dimensional Ca(H2olz)?2 H2O sheets, and a three-dimensional metal-organic framework Ca(H2olz)?2DMF (DMF=N,N-dimethylformamide). The framework undergoes structural changes in response to solvent, forming a dense Ca(H2olz) phase when exposed to aqueous HCl. The compounds Ca(H2olz)?x H2O (x=0, 2, 4) were each pressed into pellets and exposed to simulated gastrointestinal fluids to mimic the passage of a pill from the acidic stomach to the pH-neutral intestines. All three calcium materials exhibited a delayed release of olsalazine relative to Na2(H2olz), the commercial formulation, illustrating how formulation of a drug within an extended coordination solid can serve to tune its solubility and performance.
