Abstract A novel series of N-aryl-3, 4-dihydro-1′ H-spiro [chromene-2, 4′-piperidine]-1′- carboxamides was identified as transient receptor potential melastatin 8 (TRPM8) channel blockers through analogue-based rational design, synthesis and screening. Details of the synthesis, effect of aryl groups and their substituents on in-vitro potency were studied. The effects of selected functional groups on the 4-position of the chromene ring were also ...
