Bucillamine (Bc) is a cysteine derivative with two SH groups,
and a homolog of D-penicillamine, a disease-modifying
antirheumatic drug (DMARD) widely used in Japan.
However, it remains unclear whether Bc repairs bone erosion
in patients with RA.
Here, we treated three RA patients with Bc who subsequently
showed radiographic repair of erosions and cysts.

Abstract
The antioxidant properties of Bucillamine (BUC), a di-thiol
compound used for treatment of rheumatoid arthritis (RA)
and its possible mode of action, were investigated.
BUC exhibits potent antioxidant activity similar to those of
trolox and ascorbic acid.
It reduces the stable free radical diphenyl-2-picrylhydrazyl
(DPPH) with IC50 of 18.5 ± 0.1 μmol, its relative antioxidant
activity by the ferric reducing ability (FRAP) is 2.07 ± 0.01
mM and by the trolox equivalent antioxidant capacity (TEAC),
1.46 ± 0.05 mM.
However, its superoxide and apparent hydroxyl radical
scavenging activities are low (IC50 at millimolar concentrations).
We found that BUC is a strong iron (II) and copper (II) chelator.
This finding is very important since these metal ions are
significantly higher in RA patients and may be involved in
oxidative stress-induced damage.
Our study suggests that BUC is a potent antioxidant which
exerts its beneficial therapeutic activities in RA patients by
metal chelation rather than by scavenging free radical species.

He might have done better if he was.
STFU ..
