However in developing countries, occupational exposure to the Carbofuran and resultant carbofuran-serum protein labeling has been reported that impacts human health and well-being.[29] Since its toxic effects are due to its activity as a cholinesterase inhibitor it is considered a neurotoxic pesticide.[citation needed] A recent study reports that carbofuran is a structural mimic of the neurohormone melatonin and could directly bind to MT2 melatonin receptor (Ki = 1.7 uM).[30] Disruption of melatonin signaling could impact the circadian rhythm balance and is linked to elevated risk of developing diabetes.[31]
