Abstract

1. This study was directed at exploring the structure-activity relationship for anandamide and certain of its analogues at the rat VR1 receptor in transfected cells and at investigating the relative extent to which anandamide interacts with CB(1) and vanilloid receptors in the mouse vas deferens. 2. pK(i) values for displacement of [(3)H]-resiniferatoxin from membranes of rVR1 transfected CHO cells were significantly less for anandamide (5.78) than for its structural analogues N-(4-hydroxyphenyl)-arachidonylamide (AM404; 6.18) and N-(3-methoxy-4-hydroxy)benzyl-arachidonylamide (arvanil; 6.77). 3. pEC(50) values for stimulating (45)Ca(2+) uptake into rVR1 transfected CHO cells were significantly less for anandamide (5.80) than for AM404 (6.32) or arvanil (9.29). Arvanil was also significantly more potent than capsaicin (pEC(50)=7.37), a compound with the same substituted benzyl polar head group as arvanil. 4. In the mouse vas deferens, resiniferatoxin was 218 times more potent than capsaicin as an inhibitor of electrically-evoked contractions. Both drugs were antagonized to a similar extent by capsazepine (pK(B)=6.93 and 7.18 respectively) but were not antagonized by SR141716A (1 microM). Anandamide was less susceptible than capsaicin to antagonism by capsazepine (pK(B)=6.02) and less susceptible to antagonism by SR141716A (pK(B)=8.66) than methanandamide (pK(B)=9.56). WIN55212 was antagonized by SR141716A (pK(B)=9.02) but not by capsazepine (10 microM). 5. In conclusion, anandamide and certain of its analogues have affinity and efficacy at the rat VR1 receptor. In the mouse vas deferens, which seems to express vanilloid and CB(1) receptors, both receptor types appear to contribute to anandamide-induced inhibition of evoked contractions.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Anandamide acts as an endovanilloid at TRPV1 and shows affinity for TRPV1 that is 5-20 fold lower than its affinity for CB1.

    “Anandamide also acts as an endovanalloid at the transient receptor potential cation channel (TRPV1) receptor.31 AEA shows affinity for TRPV1 that is 5-20 fold lower than its affinity for CB1.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
