1/ $PVCT’s Modernized #SmallMolecule #RoseBengal: A #DrugSubstance, and #ActivePharmaceuticalIngredient for 21st Century #DrugDevelopment. A THREAD.
2/ “Everyone” seems to know or understand #RoseBengal, but do they (you) really?
3/ #RoseBengal is a small molecule (i.e., <1,000 Daltons*), but a “heavy” one at 973.67 Da or g/mol. It is heavy because of its four iodides, which comprise 52% of its molecular weight.
While COVID19 is grabbing world attention, another global public health threat is still rising in the wings - #AMR. By 2050 AMR could cause 10 million deaths if left unchecked. AMR is not new and its history stretches back long before penicillin. whatisbiotechnology.org/index.php/exhi… /1 
The first case of drug resistance was noted in 1907 by #PaulEhrlich, when he observed mice infected with Trypanosoma brucei developed resistance with repeated doses of #Salvarsan, the first compound found to have antimicrobial activity. whatisbiotechnology.org/index.php/exhi… /2
Another drug spotted to cause resistance was Optochin, an antimicrobial agent used to treat pneumonia. The first instance of resistance was noted in mice, infected with pneumococcal bacteria, in 1910, and then in humans in 1913. /3
