The Wittig reaction of 3-isopropyl-4-methoxybenzaldehyde and 2,3-dimethylbenzylphosphonium bromide afforded the corresponding stilbene mixture 16. Oxidative photocyclization of stilbene 16 with iodine facilitated the first total synthesis of 7-isopropyl-6-methoxy-1,2-dimethylphenanthrene, multicaulin (1). The O-demethylation of 1 with BBr3 afforded the 7-isopropyl-1,2-dimethylphenanthren-6-ol, O-demethylmulticaulin (2).

TLDR
Four multicaulin and miltirone-like phenanthrene derivatives were synthesised and evaluated as antituber tuberculosis agents and the best antituberculosis activity was exhibited by 2-isopropylphenanthrene-3-ol.

Norditerpenoids and diterpenoids from Salvia multicaulis with antituberculous activity.
TLDR
From the roots of Salvia multicaulis, four new aromatic norditerpenoids, multicaulin, 12-demethylmulticauline, multiorthoquinone, and 12-methyl-5-dethydrohorminone were isolated, as well as a new pimarane diterpenoid, salvipimarone, which was found to be significantly active.

TLDR
Four abietane-type terpenoids, including two known royleanones and two new, rearranged 20-norabietanes, were isolated from the roots of the Iranian medicinal plant Salvia hydrangea DC, and oleanolic acid caused transformation of erythrocytes into stomatocytes in the concentration range where the in vitro antiplasmodial activity was observed.

A functionally orthogonal ligand-receptor pair created by targeting the allosteric mechanism of the thyroid hormone receptor.
TLDR
The mutant TRbeta(H435A) is nonresponsive to physiological concentrations of T3 but can be activated by the synthetic hormone analogue QH2 which potently activates His435-->Ala mutant at concentrations that do not activate the wild-type receptors TRalpha and TRbeta.
