Zaltoprofen and its novel analogues exhibit dual targeting of COX-2 and PPAR-γ, providing a strategy to alleviate lipopolysaccharide - induced acute lung injury. (PubMed, Biochem Pharmacol) - "The present study also examined the effect and the cellular and molecular mechanisms of ZPF, M2 and the novel analogues on LPS-induced ALI in vitro and in vivo, through the dual targets of COX-2 and PPAR-γ. The findings of this study suggest that the STSBPT strategy could assist as a probable multi-target medicinal drug screening strategy, and ZPF, its main metabolite M2 and its novel analogues could serve as potential therapeutic agents for the treatment of acute lung injury, through the both COX-2 and PPAR-γ molecular signalling targets."

Development, in vitro and in vivo evaluation of film forming solutions for transdermal drug delivery of Zaltoprofen. (PubMed, J Biomater Sci Polym Ed) - "In addition, significantly elevated (ANOVA, p < 0.001) analgesic effect was noted in the hot plate test in rats treated with F13 compared to the standard for 12 h proving the superior efficacy of F13. Thus, PFFS by virtue of "in situ evaporative metamorphosis" induced supersaturation can be an attractive platform to deliver ZAL transdermally."

Anti-tumor effect of zartoprofen, a non-steroidal anti-inflammatory drug, targeting PPARγ (peroxisome proliferator-activated receptor gamma) on chondrosarcoma. (ASCOBT 2024) - "Zaltoprofen suppressed tumor progression by inhibiting cell proliferation, migration, and invasion with induction of PPARγ expression in chondrosarcoma cells. The suppressing effect on tumor progression by zaltoprofen was also observed in vivo. Zaltoprofen induced PPARγ expression and MMP2 downregulation in clinical specimens with expected antitumor effects."

Effects of acidic non-steroidal anti-inflammatory drugs on human cytochrome P450 4A11 activity: Roles of carboxylic acid and a sulfur atom in potent inhibition by sulindac sulfide. (PubMed, Chem Biol Interact) - "Sulindac sulfide, ibuprofen, and flurbiprofen effectively decreased the luciferin-4A O-demethylase activity of HLMs and recombinant CYP4A11 (inhibition rates of 30-96% at an inhibitor concentration of 100 μM), while salicylic acid, aspirin, diclofenac, mefenamic acid, indomethacin, etodolac, ketoprofen, loxoprofen, S-naproxen, pranoprofen, zaltoprofen, and oxaprozin exhibited weaker inhibitory activity (inhibition rates up to 23%). The present results indicate that sulindac sulfide is a potent inhibitor of CYP4A11. These results and the molecular modeling of CYP4A11 with sulindac sulfide and its oxidized forms suggest that a sulfur atom of sulindac sulfide as well as its carboxylic acid play important roles in the inhibition of CYP4A11."

Anti-inflammatory and arthritic activity of zaltoprofen compared to piroxicam in murine models. (PubMed, Bioinformation) - "However, in the chronic inflammation model, zaltoprofen 10 mg/kg and 20 mg/kg doses of the test compound showed a significant reduction in chronic inflammation, comparable to the negative control (NaCl 10 ml/kg), although the potency was lower than the positive control (piroxicam 10 mg/kg) (P 0.05). Thus, zaltoprofen shows significant anti-inflammatory and arthritic effects in both acute and chronic models by inhibiting various inflammatory mediators."

A comparative study of effects of curcumin and its nanoparticles on the growth, immunity and heat stress resistance of Nile tilapia (Oreochromis niloticus). (PubMed, Sci Rep) - "Six diets were supplemented with three levels of nano-curcumin (50 (CN50), 100 (CN100), 200 (CN200) mg kg diet) or free-curcumin (50 (C50), 100 (C100), 200 (C200) mg kg diet), and the control diet was left without an additive (CON)...After the heat stress, ALT, AST, IgM, C3, C4, cortisol and glucose increased. Thus, nano-curcumin is more effective than its free-form in enhancing the resistance to heat stress, inducing innate immunity, lowering the stress indicators and promoting growth performance of Nile tilapia with the best concentration at 100 mg kg diet."

Pt/CN50 that was synthesized with the 50:50 solvent mixture exhibited the highest hydrogen production rate of 590.9 µmol gh, while the hydrogen production rates of Pt/CN0 (with pure ethanol solvent) and Pt/CN100 (with pure water solvent) were 462.7, and 367.3 µmol gh, respectively."

Sustainable and efficient skin absorption behaviour of transdermal drug: The effect of the release kinetics of permeation enhancer. (PubMed, Int J Pharm) - "The lower variance of an innovative parameter permeation enhancement coefficient (C) represented the relatively sustainable and effective enhancement effect and was listed as followed: 0.20 (Zaltoprofen (ZPF)), 0.31 (Diclofenac (DCF)), 0.27 (Indomethacin (IMC)), 0.07 (Azasetron (AST)), 0.11 (Oxybutynin (OBN)) and 0.06 (Donepezil (DNP)). In conclusion, zero-order release kinetic of POCC lead to sustainable and efficient penetration enhancement efficiency on basic drug, while the Higuchi release kinetic showed opposite effect for acidic drugs. A deep understanding of release kinetics of enhancer and its enhancement efficiency may drive the ideal selection of permeation enhancers and rational optimization of transdermal patches."

Nitrous oxide, methane emissions and grain yield in rainfed wheat grown under nitrogen enriched biochar and straw in a semiarid environment. (PubMed, PeerJ) - "The treatments were: CN-control (zero-amendment), CN -50 kg ha N, CN-100 kg ha N, BN -15 t ha biochar, BN-15 t ha biochar + 50 kg ha N, BN-15 t ha biochar + 100 kg ha N, SN -4.5 t ha straw, SN -4.5 t ha straw + 50 kg ha N and SN-4.5 t ha straw + 100 kg ha N. Fluxes of NO, CH and grain yield were monitored over three consecutive cropping seasons between 2014 and 2016 using the static chamber-gas chromatography method...These results indicate the dependency of crop yield, NO and CH emissions on soil quality and imply that crop productivity could be increased without compromising on environmental quality when biochar is applied in combination with N-fertilizer. The practice of applying biochar with N fertilizer at 100 kg ha N resulted in increases in crop productivity and reduced NO and CHsoil emissions under dryland cropping systems."
