Some new N-monocarbamoyl symmetrical diamines have been prepared by the addition of symmetrical amines to isocyanates or isothiocyanates. 2,6-Diaminopyridine (1), (1R,2R)-1,2-diaminocyclohexane [(1R,2R)-2], meso-1,2-diaminocyclohexane (meso-2), or (1R,2R)-1,2-diphenylethylenediamine (3) were used as the starting symmetrical diamine frameworks. All of the newly synthesized compounds were subjected to an evaluation of antiviral activity with herpes simplex virus (HSV)-1. N-Monocarbamoyl 2,6-diaminopyridines (5a, b) showed significant antiviral activity (EC50=17.0, 6.2 μg/ml) comparable to that of N-monododecanoyl 2,6-diaminopyridine (A2). As a result, compound 5a showed a better selectivity index (CC50/EC50 = ca. 10.0) than that of A2.
一些新的 N-单氨基甲酰基对称二胺是通过将对称胺加到异氰酸酯或异硫氰酸盐中制备的。2,6-二氨基吡啶(1)、(1R,2R)-1,2-二氨基环己烷[(1R,2R)-2]、介-1,2-二氨基环己烷(介-2)或(1R,2R)-1,2-二苯基乙二胺(3)被用作起始对称二胺框架。所有新合成的化合物都对单纯疱疹病毒(HSV)-1 的抗病毒活性进行了评估。N-monocarbamoyl 2,6-二氨基吡啶(5a、b)显示出显著的抗病毒活性(EC50=17.0,6.2 μg/ml),与 N-monodecanoyl 2,6-二氨基吡啶(A2)相当。因此,化合物 5a 的选择性指数(CC50/EC50=约 10.0)优于 A2。
