Five new mexicanolide-type tetranortriterpenoids, tigloylseneganolide A (1), 2'R-methylbutanoylproceranolide (2), 2'S-methylbutanoylproceranolide (3), 2'R-cipadesin A (4), and 2'R-cipadesin (6), as well as the known 2'S-epimers of 4 and 6 (5 and 7), together with six other known limonoids, were isolated from the seeds of Cipadessa baccifera. The structures of these compounds were elucidated on the basis of spectroscopic analyses and chemical methods. 1H NMR-based conformational analysis was… Expand
Tetranortriterpenoids from the Leaves of Cipadessa cinerascens.
TLDR
Seven known and six new tetranortriterpenoids, cineracipadesins A-F (1-6), were isolated from the leaves of Cipadessa cinerascens and the ability of compounds 1-7 to inhibit the growth of the P-388 murine leukemia cell line was evaluated. Expand
Methyl angolensate and mexicanolide-type limonoids from the seeds of Cipadessa baccifera.
TLDR
Results indicated that compounds 4, 10, and 14 displayed potent cytotoxic activity against B-16, ACHN cell lines with an IC50 values of 8.51 and 7.0 μg/mL, respectively. Expand
Cipadessains A–K, eleven limonoids from the fruits of Cipadessa cinerascens
Eleven new mexicanolide-type limonoids, cipadessains A–K (1–11), were isolated from the fruits of Cipadessa cinerascens (Pellegr) Hand.-Mazz. Their planar structures were determined based on IR, UV,Expand
New seco-limonoids from Cipadessa baccifera: Isolation, structure determination, synthesis and their antiproliferative activities.
A comprehensive reinvestigation of chemical constituents from CHCl3-soluble extract of Cipadessa baccifera led to the isolation of two new limonoids 1, 2 together with six known compounds 3-8. TheirExpand
Limonoids with Anti-HIV Activity from Cipadessa cinerascens.
Sixteen new limonoids, named ciparasins A-P (1-16), comprising three structural categories of trijugin-type (1-7), cipadesin-type (8-15), and prieurianin-type (16) compounds, as well as 15 knownExpand
Mexicanolide-type limonoids from the twigs and leaves of Cipadessa baccifera.
TLDR
Two rare naturally occurring mexicanolide-type limonoids bearing an α,β-unsaturated-γ-lactone motif at C-17 are found, and cipaferen R is the first degraded tetranortriterpenoid derivative featuring an unique acetyl group atC-17. Expand
Absolute stereostructure of Andirolides A–G from the flower of Carapa guianensis (Meliaceae)
A new gedunin, three new mexicanolides and three new phragmalin-type limonoids named Andirolides A (1), B (2), C (3), D (4), E (5), F (6), and G (7) were isolated from oil of the flower of CarapaExpand
Cipadessin-type limonoids from the leaves of Cipadessa baccifera
Abstract Four new cipadessin-type limonoids, cipaferens A–D ( 1 – 4 ), and two known compounds ( 5 and 6 ) were isolated from the ethyl acetate-soluble extract of Cipadessa baccifera leaves. TheExpand
Limonoids from the Fruits of Khaya ivorensis
TLDR
Two new limonoids, namely 14,15-didehydroruageanin A and 3-O-methyl- butyrylseneganolide A, were isolated from the fruits of Khaya ivorensis along with six known limonoid compounds and evaluated for their cytotoxicity against five tumor cell lines. Expand
