Prof. Ruchi Anand has been awarded the 2023 Sun Pharma Science Foundation Research Award for Pharmaceutical Sciences, for her significant research contributions in the realm of new therapies to combat drug resistance towards design and development of new drugs.
Her research focuses on understanding antibiotic resistance and developing therapies to combat it. In her pursuit of understanding resistance determinants, Prof. Anand focused on discovering novel drug targets and drugs that can successfully “reverse resistance”. For instance, she has been involved in developing drug candidates that inhibit select pathogenic ribosomal methyltransferases. These enzymes are present in drug resistant bacteria such as Staphylococcus aureus strains, where they posttranslational modify the protein synthesis machinery, the ribosome, in the cell rendering the bacteria resistant to several different antibiotics. In particular she focused on erythromycin methyltransferases which methylate a select adenine base on the bacterial ribosome and renders them resistant to more than 50 different macrolide, linconamide and streptogramin class of drugs. To address this challenge, she identified a unique allosteric pocket in these enzymes and successfully uncovered selective compounds that inhibit function of these enzymes. She has also been involved in developing modified antibiotic conjugates that bypasses the resistance mechanism and allows these antibiotics to complete inhibit the methyltransferase pathway. This breakthrough reinstates sensitivity to existing antibiotics, effectively "reversing resistance." Her investigation further extends to the efflux mechanisms of antibiotics in multidrug-resistant bacteria, where her goal is to develop inhibitors for tetracycline receptor class of efflux pumps. Through structural biology and concerted fields, she revealed insights into allosteric relay, providing essential information for the design of effective efflux pump inhibitors.
