Graphical Abstract:


Background: A wide range of heterocyclic steroidal derivatives gained a special attention due to their wide range of pharmacological activities especially the therapeutic activities. Many pharmacological drugs containing the steroid nucleus are known in the market.

Objective: Our main aim of this work was to synthesise a series of heterocyclic compounds especially thiophene and thienopyridine derivatives containing the estrone nucleus. The synthesized compounds posses antitumor and kinases inhibitions.

Method: Thiophene derivatives of estrone were synthesized and used for further heterocyclization reactions through the reaction with the different reagent.

Results: Antiproliferative evaluations and c-Met kinase, Pim-1 kinase inhibitions were performed where some compounds revealed high activities.

Conclusion: Compounds that showed high antiproliferative activity and c-Met- kinase inhibitions were tested for all compounds. The most promising compounds 3b, 5c, 6c, 8d, 8f, 13e, 13f, 18b and 20d were further investigated against tyrosine kinase (c-Kit, Flt-3, VEGFR-2, EGFR, and PDGFR). Compounds 6b, 13b, 16b and 16c were selected to examine their Pim-1 kinase inhibition activity where compounds 11c, 18b and 20f showed high activities. Structure-Activity Relationship (SAR) was rationalized by looking at the varying structural features of the molecules.

Keywords: Estrone, thiophene, anti-proliferative activities, kinase inhibition, HTRF kinase, Pim-1 kinase.
