The term C6-C12 aryl refers to aromatic ring groups with 6 to 12 carbon atoms that do not contain heteroatoms on the ring, such as phenyl, naphthyl, etc. The term C6-C10 aryl has a similar meaning.

    [0050] In the present invention, the terms aromatic heterocycle or heteroaryl have the same meaning, referring to a heteroaromatic group containing one or more heteroatoms. The heteroatoms referred to here include oxygen, sulfur, and nitrogen. For example, furyl, thienyl, pyridyl, pyrazolyl pyrazole, pyrrolyl, N-alkylpyrrolyl, pyrimidinyl, pyrazinyl, imidazolyl, tetrazolyl, etc. The heteroaromatic ring can be fused onto an aryl, heterocyclyl, or cycloalkyl ring, wherein the ring connected to the parent structure is a heteroaromatic ring. Heteroaryl can be optionally substituted or unsubstituted.

    [0051] In the present invention, the term 3-12 membered heterocyclyl refers to a saturated or unsaturated 3-12 membered ring group containing 1-3 heteroatoms selected from oxygen, sulfur, and nitrogen on the ring, such as dioxolane. The term 3-7 membered heterocyclyl has a similar meaning.

    [0052] In the present invention, the term substituted refers to one or more hydrogen atoms on a specific functional group are substituted by a specific substituent. The specific substituents were those described in the preceding text or those that appear in various Examples. Unless otherwise specified, a substituted group may have a substituent selected from a specific group at any substitutable site of the group, which may be the same or different at each position. A cyclic substituent, such as a heterocycloalkyl, can be attached to another ring, such as a cycloalkyl, to form a spirobicyclic system, for example, where two rings share a common carbon atom. Those skilled in this field should understand that the expected combinations of substituents in the present invention were those that were stable or chemically achievable. The substituents include (but are not limited to): C1-8 alkyl, C2-8 alkenyl, C2-8 alkynyl, C3-8 cycloalkyl, 3- to 12 membered heterocyclyl, aryl, heteroaryl, halogen, hydroxyl, carboxyl (COOH), C1-8 aldehyde, C2-10 acyl, C2-10 ester group, amino, alkoxy, C1-10 sulfonyl, etc.

    Example of Pharmacological Activity Test

    Example 1: Activity Determination of the Compound of the Present Invention for Improving Blood Flow

    [0209] We used a laser speckle test blood flow model to test the activity of compounds in improving cerebral blood flow in mice. The principle is to measure the intensity changes of flowing blood through laser speckle technology, reflecting real-time cerebral blood flow; By comparing the changes in blood flow before and after administration in mice, the effect of compounds on improving blood flow can be detected.

    [0210] The experimental process is shown in FIG. 1. The experimental mice were anesthetized for 30 seconds and fixed on a rack. After waiting for 2 minutes for the baseline light intensity data to stabilize, the brain blood flow light intensity data of the mice were recorded for 10 minutes without administration. Subsequently, the test compound was injected intraperitoneally and the cerebral blood flow and light intensity data of mice were recorded within 60 minutes after administration. Comparing the changes in light intensity before and after administration can reveal the degree of changes in cerebral blood flow in mice.

    [0211] Through the laser speckle model mentioned above, we conducted preliminary tests on the activity of the compound in improving cerebral blood flow in mice. In this experiment, ferulic acid (FA) was used as a positive control. The blood flow improvement effect of the compound is shown in FIG. 2. Multiple compounds have shown significant improvement effects on cerebral blood flow in this model. At a dose of 5 mg/kg, compound 9 can increase cerebral blood flow in mice by about 10%, and compound 16 can increase it by about 20%. At a dose of 20 mg/kg, compounds 30 and 59 increased mouse cerebral blood flow by about 10%, compounds 5, 6, 26, 28, 29, 35, 43, and 58 all increased mouse cerebral blood flow by about 20%, compounds 16, 57, and 86 increased mouse cerebral blood flow by about 30%, compounds 27, 84, and 104 increased it by about 40%, and compound 83 increased mouse cerebral blood flow by 50% to 60%. Overall, the patented compound has good development prospects.

    Example 2 Determination of Pharmacokinetic Parameters in the Compound of the Present Invention

    [0212] Male ICR (CD-1) mice were divided into two groups, with three mice in each group. Each group was orally administered 20 mg/kg of the test substance or intravenously injected with 5 mg/kg of the test substance, blood was collected before administration, and 0.25 h, 0.5 h, 1 h, 2 h, 4 h, 8 h, and 24 hours after administration, respectively, and centrifuged immediately to obtain plasma, and the drug concentration in the plasma was determined using liquid chromatography tandem mass spectrometry.

    [0213] The pharmacokinetic parameters in mice were shown in the following table. In mice, the oral bioavailability of compounds 27 and 83 was 14.7% and 17.4%, respectively, indicating good pharmacokinetic properties.
