T185 0-205 Sentence denotes With the aim of establishing whether CLQ and CLQ-OH could prevent the attachment of SARS-CoV-2 to plasma membrane gangliosides, the initial NTD–GM1 complex was superposed with a drug–GM1 complex (Fig. 9 ).
T186 206-269 Sentence denotes To improve clarity, the ganglioside is not presented in Fig. 9.
T187 270-459 Sentence denotes This superposition shows that the NTD and the drug (CLQ-OH in this case) share the same spatial position when bound to GM1, so GM1 cannot bind the viral protein and the drug simultaneously.
T188 460-684 Sentence denotes This is due to the fact that the NTD and the drugs (CLQ and CLQ-OH) bind to GM1 with a similar mechanism controlled by a dyad of functional interactions: a hydrogen bond and a geometrically perfect CH-π stacking interaction.
T189 685-821 Sentence denotes In the case of the NTD, the hydrogen bond involves Asn-167, whereas CH-π stacking is mediated by the aromatic ring of Phe-135 Fig. 6(b).
T190 822-914 Sentence denotes On one hand, Asn-167 establishes a network of hydrogen bonds with the GalNAc residue of GM1.
T191 915-1017 Sentence denotes On the other hand, the flat aromatic ring of Phe-135 stacks on to the cycle of the Glc residue of GM1.
T192 1018-1137 Sentence denotes In the case of CLQ and CLQ-OH, it is the nitrogen-containing ring of the drug that stacks on to the Glc ring Fig. 4(c).
T193 1138-1244 Sentence denotes Note that both the Phe-135 (in red) and CLQ-OH (in green) rings are located in the same position (Fig. 9).
T194 1245-1379 Sentence denotes The other CLQ-OH molecule, which covers the tip of the sugar part of the ganglioside, interacts with the GalNAc ganglioside Fig. 4(b).
T195 1380-1489 Sentence denotes When the NTD is bound to the ganglioside, the side chain of Asn-137 is found in this exact position (Fig. 9).
T196 1490-1658 Sentence denotes Thus, once two CLQ-OH (or two CLQ) molecules are bound to a ganglioside Fig. 4(e,f), any binding of a SARS-Cov-2 S protein to the same ganglioside is totally prevented.
T197 1659-1795 Sentence denotes The energy required to overcome this steric incompatibility is estimated to be several hundred kJ.mol−1, which is far too high to occur.
T198 1796-1854 Sentence denotes Fig. 9 Mechanism of action of hydroxychloroquine (CLQ-OH).
T199 1855-1961 Sentence denotes The N-terminal domain (NTD) bound to GM1 was superposed onto GM1 in interaction with two CLQ-OH molecules.
T200 1962-2234 Sentence denotes The models only show the NTD and both CLQ-OH molecules (not GM1, to improve clarity). (a,b) The aromatic ring of F-135 (in red), which stacks onto the glucose cycle of GM1, overlaps the aromatic CLQ-OH rings (in green) which also bind to GM1 via a CH-π stacking mechanism.
T201 2235-2670 Sentence denotes The N-137 residue of the NTD interacts with the N-acetylgalactosamine residue of GM1, but this interaction cannot occur in the presence of CLQ-OH as this part of GM1 is totally masked by the drug. (c,d) Superposition of the NTD surface (in purple) with the two CLQ-OH molecules bound to GM1, illustrating the steric impossibility that prevents NTD binding to GM1 when both CLQ-OH molecules are already interacting with the ganglioside.
