ROS is also known to protect the cells from foreign pathogens due to their oxidative nature. Herein we have taken two different approaches to study them. In the first chapter, we discuss an improved synthesis of meayamycins, that are powerful modulators of the spliceosome and are used as tools to study splicing mutations. We examined a new enantioselective reduction of prochiral ketone, en route to the synthesis of meayamycin B. We also described the synthesis of new analogue keto-meayamycin D that probes the potency of meayamycins containing other electrophilic functionalities instead of the epoxide group. In the second chapter, we discussed the need for new fluorescent turn-on probes for a better understanding of how ROS participates in cellular processes. We describe the syntheses of two new probes for the detection of H2O2 that is based on a Mislow-Evans rearrangement. We further studied the stability and kinetics in detail and how they could be beneficial in complimenting the existing probes. Finally, we examined the effect of serum on the Mislow-Evans rearrangement, which is the underlying principle for the H2O2 detection. date: 2018-01-31 date_type: published pages: 201 institution: University of Pittsburgh refereed: TRUE etdcommittee_type: committee_chair etdcommittee_type: committee_member etdcommittee_type: committee_member etdcommittee_type: committee_member etdcommittee_name: Koide, Kazunori etdcommittee_name: Curran, Dennis P. etdcommittee_name: Floreancig, Paul E. etdcommittee_name: Edwards, W.
