Defensin Mimetics - Seems it is a known subject to scientist - However as you can see from the link below - searching for chemical compounds that meet these attributes is not easy. The study below shows that the group identified 2 compounds (BAS00127538 & 1499-1221 ) that showed promise as defensing memetics action. http://www.plospathogens.org/article/info%3Adoi%2F10.1371%2Fjournal.ppat.1003732 Looking at this - it seems Polymedix OR Uuniv of Pennsylvania was way ahead of others in this study. Again - it seems people just do not know about B and stage of testing. Hope B gets proper visibility
