This supplementary information provides the NMR spectra of antarlide F, antarlide G, and antarlide H in Acetone-d6 solvent, along with their respective COSY, HMQC, HMBC, and NOESY spectra. Additionally, it includes a PDA chromatogram showing the photoisomerization of antarlide A and antarlide F after exposure to room light for 2 hours.
