Quinilone formation?

Two weeks ago, I started taking CoQ-10 (1,4-benzoquinone) and 2 days ago I started taking PQQ (pyrroloquinoline quinone). The names of these supplements sound very similar to quinolones.

Do you think these supplements could cause similar joint issues like quinolone antibiotics? I've been working on healing some leg muscle injuries and I thought these supplements could help heal things.

However, looking back on this, I noticed my knee started a grinding noise last week and since the first night of PQQ my knees have ached, which was my initial symptom from Cipro years ago. I'm going to stop taking these supplements and see what happens. This could all be coincidental but these chemical names have me wondering if they could easily convert to quinolones in the body or cause similar side effects.

Thank you for any insight you can share.
