Isoquinoline is an analog of pyridine. Isoquinoline-based alkaloids, such as p-tolyl bisisoquinoline, phthaloyl isoquinoline, and naphthyl isoquinoline, exhibit anticancer activity. Berberine, an isoquinoline alkaloid, exerts anti-inflammatory effects in diabetic mice by downregulating the gene expression ratios of pro-/anti-inflammatory and Th1/Th2 cytokines. Additionally, some isoquinoline-based compounds also possess antidepressant, antibacterial, antimalarial, and anti-HIV activities.

In Vitro

Isoquinoline alkaloids exhibit inhibitory activity against Plasmodium falciparum (drug-resistant mutant strain K1). Among them, dehydrodiscretine and berberine have IC₅₀ values of less than 1 μM, while sallocrytopine, columbamine, dehydroocoteine, jatrorrhizine, norcorydine, thalifendine, and ushinsuninehad have IC₅₀ values ranging from 1 to 10 μM^[5].
Berberine (A kind of Isoquinoline) (20-80 μM, 14 days) exerts neuroprotective effects against brain ischemia by modulating apoptotic protein changes and reducing microglial activation^[6].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis^[6]

Cell Line:

Hippocampal neurons (rat)
Concentration:

20-80 μM
Incubation Time:

14 days
Result:

Led that the Bax/Bcl-2 ratio was altered, reduced expression of apoptotic marker Caspase-3.

In Vivo

The isoquinoline compound, 7-fluoro-1,3-diphenylisoquinoline-1-amine (FDPI) (0.1 and 1 mg/kg, i.g., once daily for 35 days) abolishes chronic unpredictable mild stress-induced depressive-like behavior in adult Swiss mice^[3].
The isoquinoline alkaloid berberine (50-500 mg/kg, i.g., once daily for 14 weeks) exerts a protective effect on spontaneous inflammation in the spleen, liver, and kidney of mice (non-obese diabetic (NOD) mice that spontaneously develop type 1) diabetes by downregulating the gene expression ratios of pro-/anti-inflammatory and Th1/Th2 cytokines^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Chronic unpredictable mild stress (CUMS)-induced depressive-like male adult Swiss mice model (25–35 g)
Dosage:

0.1 and 1 mg/kg
Administration:

Intragastric administration (i.g), once daily for 35 days
Result:

Effectively abolished depressive-like behavior in CUMS-exposed mice, improving self-care and motivation in the splash test and reducing immobility time in the TST and modified FST.
Did not affect spontaneous locomotion, ruling out psychostimulant interference.
Prevented the CUMS-induced increase in NF-κB and pro-inflammatory cytokines (TNF-α, INF-γ, IL-1, IL-6) in the prefrontal cortex and serum, while restoring IL-10 levels.
FDPI prevented the CUMS-induced elevation of corticosterone and ACTH, counteracting the increase in adrenal weight, suggesting regulation of HPA axis hyperactivity.
Prevented the CUMS-induced increase in 5-HT uptake in synaptosomes, indicating modulation of serotonergic neurotransmission.
Counteracted the CUMS-induced increase in pro-BDNF and decrease in TrkB in the prefrontal cortex, suggesting a role in neuroplasticity restoration.
Exerted antidepressant-like effects at lower doses than paroxetine, but its superiority over paroxetine could not be confirmed due to different administration routes (intragastric vs. intraperitoneal).
Demonstrated potential as a multi-target antidepressant, with effects mediated by anti-inflammatory actions, HPA axis modulation, serotonin system regulation, and neurotrophic signaling pathways. Further studies on chronic administration and side effects are needed.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
