Novel ester tethered dihydroartemisinin‐3‐(oxime/thiosemicarbazide)isatin hybrids as potential anti‐breast cancer agents: Synthesis, in vitro cytotoxicity and structure–activity relationship
A series of ester tethered dihydroartemisinin-3-(oxime/thiosemicarbazide)isatin hybrids 7a–p were designed, synthesized, and assessed for their antiproliferative activity against MCF-7, MDA-MB-231, MCF-7/ADR, and MDA-MB-231/ADR breast cancer cell lines. Among them, hybrids 7a,f (IC50: 1.33–3.84 µM) showed potent activity against triple-negative (MDA-MB-231 and MDA-MB-231/ADR) breast cancer cell lines

that most of the ester-tethered artemisinin-isatin hybrids (IC50: 1.53–51.39 µM) showed activity against CCRF-CEM cells, with six of them (IC50: 3.47–9.52 µM) being >10.5 times more potent than artemisinin (IC50: >100 µM). Notably, hybrid 7i (IC50: 3.82, 1.53, and 22.71 µM) exhibited promising activity against all three tested leukemia cell lines. Hybrid 7i was 3.2 and 2.5 times more active than Adriamycin

A simple and efficient Michael addit ion of isatin to acrylate in the presence of KOH was described. Methyl β-(2,3-dioxoindolin-1-yl) propanoate was synthesized firstly by the addition of isatin to methyl acrylate in a feasible approach using 10% KOH as catalyst in DMF with the highest yield of 72.5% under the optimized conditions. A series of β-(2,3-dioxoindolin-1-yl) propanoate derivatives was synthesized according to this approach and gave moderate to relative high yields. The directive distinct color changes in this reaction were illuminated by the reaction mechanism analysis.

work, we reported the design, synthesis, and in vitro cytotoxicity evaluation of novel dihydroartemisinin-isatin hybrids tethered via different length of esters against MCF-7, MDA-MB-231, MCF-7/ADR and MDA-MB-231/ADR breast cancer cell lines. The preliminary results showed that the majority of the hybrids exhibited good anti-breast cancer cell activity. In particular, hybrids 7 g and 7n not only were
