5-Amino-1-substituted-1H-pyrazole-4-carbonitrile derivative 1 was used as a precursor for preparation of some novel substituted pyrazole and pyrazolo[3,4-d]pyrimidine derivatives 2-10. Furthermore, the preparation of sugar hydrazone derivatives 11a,b, 12a,b and their annelated C-nucleosides 13a,b was described. Some of the prepared products revealed promising antiviral activity against herpes simplex virus type-1 (HSV-1) in comparison to Acyclovir as a control.
