The pseudolaric acids are diterpenoids isolated from the root bark of Pseudolarix amabilis, or the golden larch. Pseudolaric acids A and B are the major antifungal and anti-angiogenic congeners of this family of compounds. This review presents the results of the isolation, biological and synthetic studies of these natural products. 127 references are cited.

Amentoflavone has been identified as a JAK2 inhibitor by structure-based virtual screening of a natural product library. In silico optimization using the DOLPHIN model yielded analogues with enhanced potency against JAK2 activity and HCV activity in cellulo. Molecular modeling and kinetic experiments suggested that the analogues may function as Type II inhibitors of JAK2.

[reactions: see text] [(Ph3P)CuH]6 effectively catalyzes the hydrostannation of activated alkynes with exclusive regioselectivity for alpha-stannation. Syn hydrostannation is observed exclusively for alkynoates. Anti or syn hydrostannation adducts are obtained as products for alkynone substrates.
