Disease relevance of manoalide

  • We, thus, studied the effect of manoalide (MLD), a PLA(2) inhibitor, on the toxin catalytic activity and its central and peripheral toxicity [1].
  • Modulation of superoxide anion generation by manoalide, arachidonic acid and staurosporine in liver infiltrated neutrophils in a rat model of endotoxemia [2].
  • The intracellular Ca2+ release and apoptosis induced by glibenclamide were significantly suppressed by treatment with phospholipase C (PLC) inhibitors (U-73122 and manoalide) or by pretreatment with pertussis toxin (PTx) [3].
  • In conclusion, concomitant administration of BSO and manoalide induces renal tubular damage and acute renal failure in rats, similar in characteristics to gentamicin-induced nephrotoxicity, whereas administration of BSO or manoalide alone did not [4].
  • To data, manoalide has been clinically evaluated in man and a new Bristol-Myers Squibb retenoid derivative may enter clinical trials for psoriasis (BMS-181162 (XVI)); however, there are no PLA2 inhibitors on the market or significantly advanced in clinical development (Table III) [5].
 

High impact information on manoalide

  • To evaluate the effects of the phospholipase A2 (PLA2) inhibitor manoalide on cartilage degradation, stromelysin expression, and inflammatory cell accumulation in rabbits treated intraarticularly with recombinant human interleukin-1 alpha (rHuIL-1 alpha) [6].
  • Pretreatment with manoalide (0.3 mg/joint) significantly inhibited PLA2 activity in the synovial fluid, prevented the loss of proteoglycan from the condylar cartilage, and reduced proteoglycan levels in lavage fluids [6].
  • The effects of the phospholipase A2 inhibitor, manoalide, on cartilage degradation, stromelysin expression, and synovial fluid cell count induced by intraarticular injection of human recombinant interleukin-1 alpha in the rabbit [6].
  • Functional assays also demonstrate that MLD and SLD block MAC-1-dependent adhesion of activated neutrophils to keyhole limpet hemocyanin at concentrations that block the surface expression of MAC-1 [7].
  • Addition of phospholipase A2 (PLA2) inhibitors (quinacrine, 4-bromophenacyl bromide, manoalide) to the perfusion medium inhibited K(+)-stimulated [3H]ACh and [3H]AA release in a dose-dependent manner [8].
 

Biological context of manoalide

  • A synthetic manoalide analogue 3(cis,cis,-7,10)hexadecadienyl-4-hydroxy-2-butenolide inhibited the enzyme with half-inhibition (IC50) at about 160 microM [9].
  • The PL inhibitors bromophenacyl bromide and manoalide abolished the release of 3H and inhibited phagocytosis of EIgG in parallel [10].
  • Manoalide inhibited hydrolysis of all three phosphoinositides by purified PI-PLC I [11].
  • The substrate kinetics of PI-PLC I suggest that manoalide does not inhibit purified PI-PLC I by simple competitive or noncompetitive inhibition [11].
  • These structure-activity relationship studies suggest that the closed ring form of manoalide is the predominant molecular species that accounts for the selective and potent inhibition of PLA2 by manoalide [12].

Associations of manoalide with other chemical compounds

 

Gene context of manoalide

  • Scalaradial and to some extent manoalide were capable of blocking the IL-1 beta-induced expression of PHGS-2 [18].
  • This conclusion is supported by the following findings: (1) ET-1-evoked AA release was inhibited by the PLA2 inhibitors dexamethasone, mepacrine and manoalide in a concentration-dependent manner [19].
  • Inhibition of other PLA2 isoforms, secretory PLA2 and calcium-independent PLA2, by manoalide and haloenol-lactone suicide substrate, respectively, does not affect this effect of AGEs relative to inhibitor-treated controls [20].
  • In A431 cells the increase in epidermal growth factor receptor-mediated Ca2+ entry and release from intracellular Ca2+ stores were blocked by manoalide in a time-dependent manner with an IC50 of 0.4 microM [15].
  • The phospholipase A2 (PLA2) inhibitors quinacrine, manoalide and scalaradial inhibit the carbachol-stimulated secretion of the amyloid precursor protein (APP) from cells transfected with the human m1 muscarinic receptor [21].
