Not many people know that polyoxometalates (POMs) discovery dates back to 1783 and that they were the D´Elhuyar brothers (Juan José D´Elhuyar(Logroño, 1754) and Fausto D´Elhuyar (Logroño, 1755) who discovered a yellow spicy/bitter tasting salt from the reaction of ammonium molybdate with phosphoric acid which is now known as ammonium 12-phosphomolybdate, (NH4)3[PMo12O40] (Figure 1). Although […]

The discovery and development of new drugs is a long and expensive process, and despite of it, essential to face present and new diseases. For small molecules, which account for the majority of the marketed drugs, the discovery process generally involves finding a starting point termed hit or lead compound. These molecules have biological activity […]
