Current efforts in the field of vitamin D are to develop 1,25(OH)2D3 analogs that exhibit equal or even increased anti-proliferative activity while possessing a reduced tendency to cause hypercalcemia. The study proposes a new, rational design of vitamin D analogs based on data available in the Protein Data Bank. Undertaken approach was to minimize the electrostatic interaction energies available...
The hybrid analogs of 1,25-dihydroxyergocalciferol (PRI-5201 and PRI-5202) were synthesized as potential anticancer agents using a convergent strategy. The analogs were designed by combining a 19-nor modification of the A-ring with the homologated and rigidified ergocalciferol-like side-chain of the previously obtained analogs PRI-1906 and PRI-1907. The strategy also allowed the novel efficient synthesis...
