Jan 18, 2019 Hydroxychloroquine Plaquenil was originally used to treat malaria and is now used mostly to treat rheumatological and dermatological diseases. Its most frequent use now is for Rheumatoid Arthritis RA and Lupus and is often very effective in mitigating the joint and arthritic symptoms these diseases can cause.

    Binding of the drug to melanin in the RPE contributes to, or prolongs, its toxic effects. This leads to disruption and damage to the photoreceptors and outer nuclear and plexiform layer, sparing the foveal center and resulting in the “bull’s eye” appearance in the late stage of the disease.

Their chemical structure is defined by a 16-membered lactone ring scaffold. Bafilomycins exhibit a wide range of biological activity, including anti-tumor, anti-parasitic, immunosuppressant and anti-fungal activity. The most used bafilomycin is bafilomycin A1, a potent inhibitor of cellular autophagy. Bafilomycins have also been found to act as ionophores, transporting potassium K+ across biological
