Paragraph 0152-0157, (2021/05/29)
A method of isolating and separating a target macromolecule, such DNA (double stranded or single stranded), RNA (double stranded or single stranded), messenger RNA, or other oligonucleotide or oligonucleoside, from a sample by binding the target macromolecule to an affinity ligand that is bound to a surface is disclosed. The method may be employed in chromatography or any other of the separation sciences.

The abnormal expression of lysine-specific histone demethylase 1 (LSD1) is associated with different cancer types, and LSD1?inhibitory activity seems to have high therapeutic potential in cancer treatment. Here, we report the design, synthesis, and biochemical evaluation of novel 5-aminotetrahydroquinoline-based LSD1 inhibitors. Among them, compounds A6, A8, B1–B5, and C4 showed preferable inhibitory effects on LSD1, with IC50 = 0.19–0.82 μM. Several potent compounds were selected to evaluate their antiproliferative activity on A549 cells and MCF-7 cells with a high expression of LSD1. The potential binding modes of the compounds were revealed through molecular docking to rationalize the potency of compounds toward LSD1. Our data recognized that the 5-aminotetrahydroquinoline scaffold may serve as a starting point for developing potent LSD1 inhibitors for cancer therapy.

Paragraph 0047; 0048, (2020/02/20)
The invention discloses a leucine aminopeptidase and monoamine oxidase-activated near-infrared fluorescent probe as well as a synthetic method and biological application thereof. The adopted syntheticmethod includes the following step: (1) synthesizing the novel leucine aminopeptidase and monoamine oxidase-activated near-infrared fluorescent probe (NML); and the biological application comprises the following step: (1) applying the probe to biological imaging and serum detection. The leucine aminopeptidase and monoamine oxidase-responsive fluorescent probe is synthesized for the first time, and the problem of low specificity of a traditional single-enzyme fluorescent probe is overcome; the fluorescent probe has near-infrared fluorescence properties, the background fluorescence signal can be effectively reduced, and the sensitivity of the probe can be improved; and the fluorescent probe has a good staining effect on living cells and high staining efficiency, and can detect cell endogenous leucine aminopeptidase and monoamine oxidase.

The targeted regulation of LSD1, which is highly expressed in a variety of tumor cells, is a promising cancer therapy strategy. Several LSD1 inhibitors are currently under clinical evaluation, and most of these inhibitors are irreversible. Here, we report the design, synthesis and biochemical evaluation of novel tetrahydroquinoline-based reversible LSD1 inhibitors. Compounds 18s and 18x, which are selective to LSD1 over MAO-A/B, exhibit excellent LSD1 inhibition at the molecular levels with IC50 = 55 nM and 540 nM, respectively. The classic Lineweaver–Burk plots revealed that compound 18s could reversibly bind the LSD1 enzyme in a noncompetitive manner. Molecular docking was used to reveal the potential binding-mode of the compounds and interpret the structure-activity relationships. Furthermore, compounds 18s and 18x significantly inhibited proliferation (IC50 = 1.13 μM and 1.15 μM, respectively) and induced apoptosis in MGC-803 cells with high expression of LSD1. Compound 18x showed acceptable liver microsomal stability. Meanwhile, 18x did not appear to inhibit CYPs at 10 μM in vitro. Remarkably, the oral administration of compound 18x can inhibit the growth of MGC-803 xenograft tumors without significant side effects. Our findings suggest that tetrahydroquinoline-based LSD1 inhibitors deserve further investigation for the treatment of LSD1 overexpressing cancer.

We report the in vitro selection of a single-stranded 72-nucleotide DNA enzyme (deoxyribozyme) that catalyzes a Friedel-Crafts reaction between an indole and acyl imidazole in good yield and in aqueous solvent. Appreciable Friedel-Crafts product requires addition of copper nitrate and the deoxyribozyme. We observe deoxyribozyme-mediated bond formation for both in cis and in trans Friedel-Crafts reactions.
