Cuminaldehyde (Cuminal) is a natural aldehyde with inhibitory effect on alpha-synuclein fibrillation and cytotoxicity. Cuminaldehyde shows anticancer activity,with a pleasant smell and contributes to the aroma of essential oils.

Cuminaldehyde抑制生长并诱导凋亡，这一点通过线粒体膜电位的耗尽，caspase-3和caspase-9的激活，以及凋亡的形态学特征得到了证明[1]。

在体内，cuminaldehyde能够减少肿瘤负担，表明cuminaldehyde可能作为化学预防或抗癌治疗的化合物。[1]

Incubated the cells in the culture plate with 96 wells at the concentration of ten thousand cells per well.?After being incubated for 24 h, we treated the cells with cuminaldehyde at the concentration of 10, 20, 40, 80, or 160 μM for 12, 24, or 48 h. Determined cell viability using the Cell Proliferation Kit II (XTT) according to the supplier's instructions.?The value of absorbance was evaluated by a spectrophotometer (Tecan infinite M200, Tecan, M?nnedorf, Switzerland) using 492 nm wavelength with a reference of 650 nm wavelength[1].

Human colorectal COLO 205 cells (5 × 10^6 cells in 200 μL of culture medium) were subcutaneously injected into the mice's flanks.?Treatment was started when the tumors reached about 75 mm^3.?Thirty-two mice were divided randomly into four groups (eight mice/group).?Cuminaldehyde-treated mice received intratumoral injection of 5, 10, or 20 mg/kg/day of cuminaldehyde in a 200 μL volume (the solutions were prepared from stock solution of cuminaldehyde in dimethyl sulfoxide and diluted into appropriate concentrations in PBS) daily.?The mice in the control group were treated with an equal volume of vehicle.?After transplantation, body weight as well as tumor size were monitored at weekly intervals.?Tumor size was measured using calipers, and tumor volume was calculated using the hemiellipsoid model formula[1]
