The article conveys some information:
Inhibition of multiple signaling pathways in a cancer cell with a single mol. could result in better therapies that are simpler to administer. Efficacy may be achieved with reduced potency against individual targets if there is synergy through multiple pathway inhibition. To achieve this, it is necessary to be able to build multi-component ligands by joining together key pharmacophores in a way which maintains sufficient activity against the individual pathways. Designed triple inhibiting ligands are explored aiming to block three completely different target types: a kinase (JAK2), an epigenetic target (HDAC) and a chaperone (HSP90). Although these enzymes have totally different functions they are related through inter-dependent pathways in the developing cancer cell. Synthesis of several complex multi-inhibiting ligands are presented along with initial enzyme inhibition data against 3 biol. target classes of interest. A lead compound, 47 (I), was discovered which had low micromolar activity for all 3 targets. Further development of these complex trispecific designed multiple ligands could result in a ‘transient drug’, an alternative combination therapy for treating cancer mediated via a single mol.
