Numerous drug treatments are available for Parkinson's disease (PD), an age-related neurodegenerative disease, but most cause serious side effects. Therefore, novel therapeutic strategies that halt disease progression and allow for long-term administration are urgently needed. Neuroinflammation critically contributes to the pathogenesis of PD. Here, we report the discovery and optimization of phloroglucinol derivatives, a novel class of anti-neuroinflammatory compounds. Structural modifications of the hit compound 3-methyl-1-(2,4,6-trihydroxyphenyl)butan-1-one produced 43 derivatives, including a preclinical candidate (compound 21), that exhibited potent in vitro anti-neuroinflammatory effects, good blood-brain barrier penetration, and desirable safety margins in mice at a median lethal dose (LD50) >5000 mg/kg. Its in vivo efficacy was demonstrated in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)- and MPTP/probenecid (prob)-induced subacute and chronic PD models, respectively, and α-synuclein transgenic mice. Mechanistic studies revealed neuroinflammation inhibition by targeting Src/phosphatase and tensin homologue deleted on chromosome 10 (PTEN)/Akt signaling might be promising. We highlighted the potential usefulness of phloroglucinol derivatives in PD treatment.

Sideroxylonal B (2c) has been synthesized through biomimetic cycloaddition of the o-quinone methide and the isopentenyl intermediates (5 and 6t), both of which were simultaneously derived from isopentenyl phloroglucinol precursor 4.
