  • The phospholipases are an extensive family of lipid hydrolases that function in cell signaling, digestion, membrane remodeling, and as venom components.{6940} The calcium-independent phospholipases (iPLA2) are a PLA2 subfamily closely associated with the release of arachidonic acid in response to physiologic stimuli. (R)-Bromoenol lactone ((R)-BEL) is an irreversible, chiral, mechanism-based inhibitor of calcium-independent phospholipase γ (iPLA2γ). Unlike (S)-BEL, (R)-BEL does not inhibit iPLA2β except at high doses of 20-30 µM.{12978} (R)-BEL inhibits human recombinant iPLA2γ with an IC50 of approximately 0.6 µM.

  • Butaprost is a structural analog of prostaglandin E2 (PGE2) with good selectivity for the EP2 receptor subtype. Butaprost has frequently been used to pharmacologically define the EP receptor expression profile of various human and animal tissues and cells.{3317,1752} Serious confusion as to the structure of butaprost was generated by Gardiner in 1986,{3326} when he reported that the epimer of butaprost showing this selective activity was the C-16 (R)-epimer (See reference {3326} and Note). Butaprost binds with about 1/10 the affinity of PGE2 to the recombinant murine EP2 receptor, and does not bind appreciably to any of the other murine EP receptors or DP, FP, IP, or TP receptors.{6640} The pharmacology of (R)-butaprost has not been carefully studied, but it is generally considered to be the less active epimer.{3178} (NOTE: In the Gardiner paper in the 1986 British Journal of Pharmacology, butaprost appears on page 46 where it is given the name TR 4979. The structure as drawn is incorrect, in that the author was using and referring to the more active C-16 epimer, which is actually 16(S). The structure on page 46 shows the structure as 16(R). It was not until the late 1990’s that careful studies both in the US and Japan correctly identified the actual configuration of C-16 in the compound called butaprost is 16(S).){3326}

  • (R)-nitro-Blebbistatin is a more stable form of (+)-blebbistatin (Item No. 13165), which is the inactive form of (–)-blebbistatin (Item No. 13013). Prolonged exposure to blue light (450-490 nm) results in degradation of blebbistatin to an inactive product via cytotoxic intermediates, which may be problematic for its use in fluorescent live cell imaging applications.{17038,24037} The addition of a nitro group stabilizes the molecule to circumvent its degradation by prolonged blue light exposure.{16725} (R)-nitro-Blebbistatin has the same stereochemistry as the inactive (+)-blebbistatin enantiomer.

  • (S)-3’-hydroxy Blebbistatin is a more stable and less phototoxic form of (–)-blebbistatin (Item No. 13013), which is a selective cell-permeable inhibitor of non-muscle myosin II ATPases.{16452,17037} (–)-Blebbistatin rapidly and reversibly inhibits Mg-ATPase activity and in vitro motility of non-muscle myosin IIA and IIB for several species (IC50s = 0.5-5 µM), while poorly inhibiting smooth muscle myosin (IC50 = 80 µM).{17036} Through these effects, it blocks apoptosis-related bleb formation, directed cell migration, and cytokinesis in vertebrate cells. However, prolonged exposure to blue light (450-490 nm) results in degradation of blebbistatin to an inactive product via cytotoxic intermediates, which may be problematic for its use in fluorescent live cell imaging applications.{17038,24037} The addition of a 3’-hydroxy group decreases the inherent fluorescence while retaining the activity of (–)-blebbistatin.{40574} (S)-3′-hydroxy-Blebbistatin has the same stereochemistry as the active (–)-blebbistatin enantiomer.

  • Acenocoumarol is a short-lived oral anti-coagulant, which, like warfarin, functions by inhibiting vitamin K epoxide reductase. It has higher intrinsic anticoagulant potency than warfarin and phenprocoumon, when evaluated in vitro. Acenocoumarol has a single chiral center that gives rise to two different enantiomeric forms. (S)-Acenocoumarol has a shorter plasma elimination half-life (1.8 hours) and faster plasma clearance (28.5 L/hour), compared to the (R)-enantiomer (6.6 hours, 1.9 L/hour).{15996} The S-enantiomer undergoes extensive first-pass metabolism during absorption from the gastrointestinal tract, whereas (R)-acenocoumarol is rapidly absorbed and provides essentially complete oral bioavailability.{15996} Perhaps related to these pharmacokinetic characteristics, (S)-acenocoumarol is less potent in vivo as an anti-coagulant than the (R)-enantiomer. As the clearance of acenocoumarol is ~20-fold faster than that for warfarin, the plasma concentrations of acenocoumarol are substantially lower than those for warfarin in patients receiving long-term treatment.
