General Experimental Procedures: Circular dichroism and UV/Vis spectra were recorded on a JASCO J-815. Microplate readings were taken on a BioTek Cytation 3 Cell Imaging Multi-Mode Reader. NMR spectra were recorded in deuterated acetone with the residual solvent peak as an internal standard (δC 28.97, δH 2.05) on Bruker Avance III 600 MHz instrument equipped with a triple resonance inverse (CP-TCI) Prodigy N2 cooled CryoProbe (600 and 150 MHz for 1 H and 13 C NMR, respectively). LR-LCMS data was obtained on an Agilent 1200 series HPLC system equipped with a photo-diode array detector and a Thermo LTQ mass spectrometer. HR-ESI-MS was carried out on either a Shimadzu LC-q-TOF Mass Spectrometer equipped with a HPLC system or an Agilent 6530 qToF equipped with a 1290 Infinity II UPLC system. HPLC purifications were carried out on Agilent 1200 series or 1260 Infinity II HPLC systems (Agilent Technologies) equipped with a photodiode array detector. Flash purification was carried out on a Biotage Selekt system. All solvents were of HPLC quality.
