A series of ring-A fused heterocycles of lupane, oleanane, ursane and dammarane
triterpenoids were synthesized and evaluated for their inhibitory activity against α …

Production of gasoline-like-fuel and diesel-like-fuel from Yang (Dipterocarpus alatus) hard
resin (HY) was studied for use as a fuel for engines using a fast pyrolysis process. HY was …

The Aglaia genus, a member of the Meliaceae family, is generally recognized to include a
number of secondary metabolite compounds with diverse structures and biological activities …

Dipterocarpus alatus Roxb. ex G. Don is widely found in Southeast Asia. Its oleo-resin has
reportedly been used in biodiesel production. Two different biodiesel production processes …

A variety of new and earlier synthesized lupane, oleanane, ursane and dammarane
triterpenoids have been investigated for their inhibitory activity against α-glucosidase. 2, 3 …

A computational NMR approach for accurate predicting the 1H/13C chemical shifts of
triterpenoid oximes featuring the screening of 144 DFT methods was demonstrated …

Diastereoselective synthesis of triterpenoid 1, 2, 4-trioxolanes by Griesbaum co-ozonolysis
was shown for the first time. Ozonolysis of 2-methoxyoximes (syn–anti-isomers mixture) of …

A series of new steroidal peroxides–3′-trifluoromethylated 1, 2, 4-trioxolanes and 1, 2, 4, 5-
tetraoxanes based on deoxycholic acid were prepared via the reactions of the Griesbaum …

Abstract Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)-are depression and
neurodegenerative diseases that target enzymes, including Alzheimer's disease (AD). With …

A one-pot synthesis of a hybrid triterpenoid-steroid molecule, hollongdione (22, 23, 24, 25,
26, 27-hexanordammar-3, 20-dion), was achieved in a yield of 89%, based on the selective …
