Sesquiterpene lactones (SLs) are natural products with a variety of biological activities. Previously, we demonstrated the cytotoxic effects of three new α-santonin derivatives on different tumor cell lines with low toxic effects upon peripheral human leukocytes. Here, we evaluated the mechanism of
DAAS is the diacetoxy acetal derivative of a-santonin and induces HL-60 cell differentiation into granulocytes. In this report, we investigated the structure-activity relationship (SAR) of DAAS derivatives in the differentiation of human HL-60 leukemia cells. Although its derivatives themselves had
Ten alpha-santonin derivatives were synthesized in moderate to high yields. Four derivatives namely 10alpha-acetoxy-3-oxo-1,7alphaH,6,11betaH-guai-4-en-6,12-olide (2), isofotosantonic acid (3), 10alpha-hydroxy-3-oxo-1,7alphaH,6,11betaH-guai-4-en-6,12-olide (4), and lumisantonin (5), were prepared by
Background: Acute lymphoblastic leukemia (ALL) is one of the most dominant malignancies among children, characterized by production of immature and dysfunctional blasts which are resistant to cytotoxic chemotherapeutic agents. Therefore, research protocols are currently focusing on discovery of
Colartin [9] and arbusculin A [11] have been synthesized from alpha-santonin [1] in 14.5% (11 steps) and 9.3% (13 steps) overall yields, respectively. Arbusculin A [11] and compounds 20, 21, and 22, which were derived from intermediate 2, showed significant cell growth inhibitory activity against
