“…It has been shown in model experiments using simple phenols that chlorine in aqueous solution brings about a small amount of oxidative coupiing (Sato and Mikawa 1960), a reaction type usuaily attributed to the involvement of radical species. However, participation of chlorine radicals to a small extent cannot be entirely excluded.…”

“…The HMBC correlations of the H-3/H-3′ resonance at δH 6.73 between C-1/C-1′ and C-2/C-2′ (δC 147.3) indicated that the methoxy group was located at C-2/C-2′ which was further supported by the NOESY correlation between the resonances for H-3/H-3′ and the methoxy group ( Figure S1). Compound 2 has been synthesized earlier, however, this is the first report of this compound as a natural product (Sato et al 1960 andHorner et al 1963). Thus, compound 2 was identified as 4,4′-dihydroxy-2,2′-dimethoxybiphenyl and was named as mckeaninabiphenyl.…”

“…So far, a few studies have been conducted on the phytochemistry and biological properties of Garcinia mckeaniana ( Auranwiwat et al, 2016 ; Ha et al, 2021 ; Nguyen et al, 2021 ; Thi Thu et al, 2021 ). The biphenyl ( 19 ) was denominated as mckeaninabiphenyl and had been synthesized previously ( Sato and Mikawa, 1960 ). This was the first time that it was reported as a natural phytochemical.…”

Clusiaceae plants contain a wide range of biologically active metabolites that have gotten a lot of interest in recent decades. The chemical compositions of these plants have been demonstrated to have positive effects on a variety of ailments. The species has been studied for over 70 years, and many bioactive compounds with antioxidant, anti-proliferative, and anti-inflammatory properties have been identified, including xanthones, polycyclic polyprenylated acylphloroglucinols (PPAPs), benzophenones, and biphenyls. Prenylated side chains have been discovered in many of these bioactive substances. To date, there have been numerous studies on PPAPs and xanthones, while no comprehensive review article on biphenyls from Clusiaceae has been published. The unique chemical architectures and growing biological importance of biphenyl compounds have triggered a flurry of research and interest in their isolation, biological evaluation, and mechanistic studies. In particular, the FDA-approved drugs such as sonidegib, tazemetostat, daclatasvir, sacubitril and trifarotene are closely related to their biphenyl-containing moiety. In this review, we summarize the progress and development in the chemistry and biological activity of biphenyls in Clusiaceae, providing an in-depth discussion of their structural diversity and medicinal potential. We also present a preliminary discussion of the biological effects with or without prenyl groups on the biphenyls.
