\t\t\tThe colleagues, from IBEC, IQAC-CSIC, UAB and IDIBELL in Barcelona and the IGF-CNRS in Montpellier in France, developed the small molecule therapeutic agent that modulates drug target protein receptors specifically at the allosteric, or non-active, site of the protein. Allosteric modulators have a number of advantages over traditional drugs, offering higher selectivity of target receptors, tunable release according to whether the undesirable protein receptor activity is present, and lower potential for toxic effects. <\/p>\n

“To build a photocontrolled modulator of a G protein-coupled receptor, we had to develop a new chemical design concept in which the photoswitch is not tethered to the drug but inserted within the pharmacophore, which is the group of atoms in the molecule of a drug responsible for its action,” explains Pau Gorostiza, group leader of IBEC’s Nanoprobes and Nanoswitches group. “We also got a bit lucky, because we not only obtained a photoswitchable GPCR ligand, but one of the most potent and selective allosteric modulators in its class.” <\/p>\n

The effects of this \u2018optopharmacological’ compound can be remotely controlled in space and time in living, wild-type organisms. This is an advantage over optogenetic manipulations, which require gene overexpression using viruses, for example. <\/p>\n

Small molecule therapeutic agents as Alloswitch-1, if they can be made available orally, could offer a competitive advantage over traditional drugs, which often affect off-target tissues and organs, leading to unwanted consequences and compromising their beneficial effects. <\/p>\n
