2-Thiouracil
2-Thiouracil (Thiouracil) is a selective neuronal nitric oxide synthase (nNOS) inhibitor with a Ki value of 20 μM. 2-Thiouracil antagonizes BH4-induced nNOS dimerization. 2-Thiouracil is also an antithyroid compound and a highly specific melanoma detector. 2-Thiouracil stimulates the growth of pea and corn root segments[1][2][3].
