The present invention is related to compound capable of regulating the activity of P2Y purinoceptor 6 signaling pathway, especially to compounds for inhibition of P2Y purinoceptor 6 polypeptide or inactivation, degradation, downregulation or intercalation of a nucleic acid encoding P2Y purinoceptor 6 or downregulation of P2Y purinoceptor 6 signaling pathway for the treatment of diseases related to energy balance as well as carbohydrate metabolism and homeostasis, preferably glucose metabolism and homeostasis. The present is also related to compounds for activation of P2Y purinoceptor 6 polypeptide or upregulation or modification for advanced transcriptional activity of a nucleic acid encoding P2Y purinoceptor 6, upregulation of P2Y purinoceptor 6 signaling pathway for gaining weight or for the treatment of diseases related to energy balance and carbohydrate metabolism and homeostasis. The invention is further related to methods of identifying said compounds suitable for the treatment of diseases related to energy balance and carbohydrate metabolism and homeostasis. The invention is further related to methods of treatment and diagnosis of diseases related to energy balance and carbohydrate metabolism and homeostasis and associated complications.
