     BGPT Odds of True

    Hypothesis claims 5-HT2BR's SEP inactive-anchor constraint also limits 5-HT2CR activation. Plausible by structural analogy to 5-HT2AR/2BR receptor-intrinsic dynamics, but no 5-HT2CR data exist in supplied records; estimate near coin-flip with wide uncertainty.

     Hypothesis Novelty


    60%

    Extending a newly published 2026 2A/2B mechanism to 2C is moderately novel; subtype-cross-conservation reasoning is standard GPCR pharmacology.

     Quick Analysis Plan


    The supplied evidence does not test this directly: the IHCH-2330 structural study covers only 5-HT2AR and 5-HT2BR, showing that divergent pharmacology arises from receptor-intrinsic extracellular/TM5 dynamics rather than ligand pose, with no 5-HT2CR structures, sequence comparisons, or functional data provided, so the proposed constraint on 5-HT2CR activation remains unverified ().


     Long Analysis Plan


    Verdict: Untested β€” key receptor missing

    The premise that IHCH-2330's antagonism at 5-HT2BR stems from receptor-intrinsic extracellular and TM5-associated dynamics (not a distinct ligand pose) is well-supported by cryo-EM comparison (). However, no supplied record contains 5-HT2CR structures, SEP-region sequence alignments, or functional assays at 5-HT2CR; the claim of "strong SEP conservation between 5-HT2AR and 5-HT2CR" is asserted, not evidenced here. Whether 5-HT2CR dynamics mirror 5-HT2BR's inactive-anchor constraint is a testable but open question. Missing: 5-HT2CR cryo-EM/MD data, Reg1 mutagenesis at 2C, and IHCH-2330 binding assays at 2CR.

    "Ligand pose determines agonism vs antagonism" β€” refuted within the source paper: comparable poses produce divergent outcomes.


    "Sequence conservation alone predicts pharmacology" β€” 5-HT2AR/2BR pose identity yet opposite outcomes shows dynamics matter.

     Science Art


    Does the SEP inactive-anchor mechanism that drives IHCH-2330 antagonism at 5-HT2BR also constrain 5-HT2CR activation, given the strong SEP conservation between 5-HT2AR and 5-HT2CR? Science Art
