Substituted phenyl[(5-benzyl-1,3,4-oxadiazol-2-yl)sulfanyl]acetates/acetamides as alkaline phosphatase inhibitors: Synthesis, computational studies, enzyme inhibitory kinetics and DNA binding studies

Substituted phenyl[(5-benzyl-1,3,4-oxadiazol-2-yl)sulfanyl]acetates/acetamides 9a-j were synthesized as alkaline phosphatase inhibitors. Phenyl acetic acid 1 through a series of reactions was converted into 5-benzyl-1,3,4-oxadiazole-2-thione 4. The intermediate oxadiazole 4 was then reacted with chloroacetyl derivatives of phenols 6a-f and anilines derivatives 8a-d to afford the title oxadiazole derivatives 9a-j. All of the title compounds 9a-j were evaluated for their inhibitory activity against human alkaline phosphatise (ALP). It was found that compounds 9a-j exhibited good to excellent alkaline phosphatase inhibitory activity especially 9h displayed potent activity with IC50 value 0.420 ± 0.012 μM while IC50 value of standard (KH2PO4) was 2.80 μM. The enzyme inhibitory kinetics of most potent inhibitor 9h was determined by Line-weaever Burk plots showing non-competitive mode of binding with enzyme. Molecular docking studies were performed against alkaline phosphatase enzyme (1EW2) to check the binding affinity of the synthesized compounds 9a-j against target protein. The compound 9h exhibited excellent binding affinity having binding energy value (?7.90 kcal/mol) compared to other derivatives. The brine shrimp viability assay results proved that derivative 9h was non-toxic at concentration used for enzyme assay. The lead compound 9h showed LD50 106.71 μM while the standard potassium dichromate showed LD50 0.891 μM. The DNA binding interactions of the synthesized compound 9h was also determined experimentally by spectrophotometric and electrochemical methods. The compound 9h was found to bind with grooves of DNA as depicted by both UV–Vis spectroscopy and cyclic voltammetry with binding constant values 7.83 × 103 and 7.95 × 103 M?1 respectively revealing significant strength of 9h-DNA complex. As dry lab and wet lab results concise each other it was concluded that synthesized compounds, especially compound 9h may serve as lead compound to design most potent inhibitors of human ALP.

Novel ketoprofen–antioxidants mutual codrugs as safer nonsteroidal anti-inflammatory drugs: Synthesis, kinetic and pharmacological evaluation

Ketoprofen belongs to one of the most common nonsteroidal anti-inflammatory drugs (NSAIDs) but its clinical usefulness has been restricted due to the high incidence of gastrointestinal complications. The release of reactive oxygen species (ROS) in NSAIDs

Synthesis and evaluation of prodrugs of ketoprofen with antioxidants as gastroprotective NSAIDs

Ketoprofen-antioxidant mutual prodrugs were synthesized to reduce the gastrointestinal effects associated with ketoprofen. For reducing the gastrointestinal toxicity, the free carboxylic group (–COOH) was temporarily masked by esterification with alcoholi

Synthesis, antimicrobial activity and in silico studies on thymol esters

Derivatisation of parent structure in terpenoids often results in enhancement of biological activity of newly obtained compounds. Thymol, a naturally occurring phenol biosynthesized through the terpene pathway, is a well known biocide with strong antimicrobial attributes and diverse therapeutic activities. We have aimed our study on a single modification of phenolic functionality in thymol in order to obtain a small focused library of twenty thymyl esters, ten of which were new compounds. All compounds were involved in in vitro antimicrobial testing. Another important aspect of current study was implementation of in silico calculation of physico-chemical, pharmacokinetic and toxicological properties, which could be helpful by giving an additional guidance in further research.

Synthesis and evaluation of antioxidant-S-(+)-ibuprofen hybrids as gastro sparing NSAIDs

Ibuprofen is one of the most popular NSAIDs for the last three decades but also known for its gastrointestinal side effects similar to other NSAIDs. To overcome this problem, we have designed and synthesized ibuprofen - antioxidant (thymol, guaiacol, eugenol, and menthol) hybrids (6-13) with and without spacer as gastro sparing agents. The hybrids have been found to be chemically stable, biolabile and exhibited retention of anti-inflammatory and analgesic activity with significant reduced ulcerogenicity as compared to the ibuprofen and ibuprofen + antioxidant physical mixture. The absence of ulcerogenicity may be attributed to antioxidants and improved physicochemical properties of these hybrid molecules.
