Biological Activity

Description Zaltoprofen is an inhibitor of COX-1 and COX-2 for treatment of arthritis.
COX-1 [1] COX-2 [1]
In vitro

Zaltoprofen binds to specific sites on the protein of the bradykinin B2 receptor, hence we have examined the effect of zaltoprofen on bradykinin-induced responses of adult DRG neurons to investigate possible interaction sites. Zaltoprofen most potently inhibits bradykinin-enhancement of capsaicin-induced Ca2+ uptake into DRG neurons. Zaltoprofen also significantly inhibits bradykinin-induced 12-lipoxygenase (12-LOX) activity and the slow bradykinin-induced onset of substance P release from DRG neurons. [1] Zaltoprofen produces an analgesic action on bradykinin-induced nociceptive responses by blocking the B(2) receptor-mediated pathway in the primary sensory neurons. Zaltoprofen completely inhibits the bradykinin-induced increase of [Ca(2+)](i), which is inhibited by B(2) antagonist D-Arg-[Hyp(3), Thi(5,8), D-Phe(7)]-bradykinin, but not by B(1) antagonist. [2] Zaltoprofen at 1nmol shows strong analgesic action on BK ( nociceptive flexor responses, whereas loxoprofen or its active metabolite loxoprofen-SRS does not. Zaltoprofen also inhibits the nociception induced by [Tyr8]-BK, a specific agonist of B2-type BK receptor, but does not affect the nociception by [Lys-des-Arg9]-BK, a specific agonist of B1-type BK receptor. [3] Zaltoprofen is a non-steroidal anti-inflammatory drug (NSAID) causes potent inhibition of cyclooxygenase-2 with fewer side effects on the gastrointestinal tract.[4]

In vivo Zaltoprofen improves the loss in body weight in both Con A-treated mice and carbon tetrachloride-treated rats. [4] Zaltoprofen (10 mg/kg) administrated at 8 h after Con A treatment is found to inhibit the Con A-induced reduction in body weight. Zaltoprofen (10 mg/kg) combined with Con A results in four times greater food intake than that in mice treated with only Con A. [5]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
