  • Leniolisib is an inhibitor of PI3Kδ (IC50 = 0.011 µM).{40219} It is selective for PI3Kδ over PI3Kα, PI3Kβ, and PI3Kγ (IC50s = 0.244, 0.424, and 2.23 µM, respectively). It inhibits phosphorylation of the PI3K target Akt in Rat-1 fibroblasts expressing P13K p110δ with an IC50 value of 0.056 µM. Leniolisib inhibits the mixed lymphocyte reaction (MLR), indicating inhibition of allogeneic T cell activation, in isolated human peripheral blood mononuclear cells (PBMCs) and isolated mouse splenocytes (IC50s = 0.079 and 0.033 µM, respectively). It also inhibits PI3Kδ-dependent B cell activation and IgM-induced B cell proliferation in isolated mouse splenocytes. Leniolisib (3 and 10 mg/kg) reduces the production of rat anti-rat collagen antibodies, as well as reduces paw swelling and joint erosion in a rat model of collagen-induced arthritis.

  • Leukadherin 1 is a small molecule allosteric activator of CD11b/CD18 that increases K562 cell adhesion to an endogenous CD11b/CD18 ligand, fibrinogen (EC50 = 4 µM).{36188} It increases adhesion and decreases de-adhesion of murine neutrophils, leading to reduced chemotaxis. It acts by reducing the rolling velocity of leukocytes in mouse cremaster muscle, decreasing the number of leukocytes recruited to injured tissue.

It also competitively inhibits YopH (Ki = 1.94 µM), a tyrosine phosphorylase secreted by Y. pestis into immune cells to block signal transduction, and anthrax lethal factor metalloproteinase, a component of anthrax toxin (IC50 = 6 µM).{36189,36187}

LTB4 ethanolamide (LTB4-EA) is a theoretical 5-LO metabolite of arachidonoyl ethanolamide (AEA). In CHO cells transfected with human BLTR1, LTB4-EA was a potent antagonist with about three times greater affinity for the receptor than LTB4 (Ki = 1.22 nM versus 3.88 nM). LTB4-EA antagonizes the LTB4-induced contractions of guinea pig lung parenchyma with an EC50 of 10 nM.{11188} LTB4-EA thus represents a potential endogenous anti-inflammatory compound functioning as a natural antagonist of BLTR1.

  • Leukotriene C4 (LTC4) is the parent cysteinyl leukotriene produced by the LTC4 synthase catalyzed conjugation of glutathione to LTA4. LTC4 is produced by neutrophils, macrophages, mast cells, and by transcellular metabolism in platelets.{781} It is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A) and exhibits potent smooth muscle contracting activity.{538} LTC4-induced bronchoconstriction and enhanced vascular permeability contribute to the pathogenesis of asthma and acute allergic hypersensitivity.{394,396} The concentration of LTC4 required to produce marked contractions of lung parenchymal strips and isolated tracheal rings is about 1 nM.{396}

The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This LTC4 MaxSpec® standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product. Note: The amount of solution added to the vial is in excess of the listed amount. Therefore, it is necessary to accurately measure volumes for preparation of calibration standards. Follow recommended storage and handling conditions to maintain product quality.
