AIM: To prepare a class of oleanolic-based compounds. BACKGROUND: Conventional drugs used to treat infectious diseases suffer from limitations such as drug toxicity and drug resistance. The resistance of microbes to antimicrobial agents is a significant challenge in treating microbial infections. Combining two or more drugs with different modes of action to treat microbial infections results in a delay in developing drug resistance by the microbes. However, it is challenging to select the appropriate choice of drugs for combination therapy due to the differences in stability and pharmacokinetic proļ¬le of the drugs...

An infectious disease of colon, recurrent Clostridium difficile infection (RCDI) is hitherto considered insurmountable leading to significant morbidity and mortality. Gut dysbiosis, generally resulting from frequent use of antibiotics is considered to be responsible for the etiopathogenesis of rCDI. Ironically, the conventional treatment strategies for the disease also include the use of anti-infective drugs such as metronidazole, vancomycin and fidaxomycin. As a result of the efforts to overcome the limitations of these treatment options to control recurrence of disease, Fecal Microbiota Transplant (FMT) has emerged as an effective and safe alternative...

BACKGROUND: Wolbachia is the most common endosymbiotic bacteria in insect-borne parasites and it is the most common reproductive parasite in the world. Wolbachia has been found worldwide in numerous arthropod and parasite species, including: insects, terrestrial isopods, spiders, mites and filarial nematodes. There is a complicated relationship between Wolbachia and its hosts and in some cases, they create a mutual relationship instead of a parasitic relationship. Some species are not able to reproduce in the absence of infection with Wolbachia...
