Synopsis of Transport Activities of TT12 Tested with Different Flavonoids as Substrates and Inhibition of TT12-Mediated C3G Transport by These Compounds
| Flavonoid Class | Compound | Transport by TT12 | Inhibition of C3G Transport by TT12 |
|---|---|---|---|
| Flavan-3-ol monomers | Epicatechin | − | − |
| Catechin | − | − | |
| Cat3G | − | + | |
| Flavan-3-ol dimers | Procyanidin B1 | − | ND |
| Procyanidin B2 | − | ND | |
| Anthocyani(di)ns | C3G | + | NA |
| Cyanidin | − | ND | |
| Flavonols | Q3R | − | − |
| Q3G | − | − |
Presence and absence of a transport activity with the corresponding substrate and of an inhibitory effect on C3G transport is indicated by + and −, respectively. ND, not determined; NA, not applicable.
