Isoquinoline
Based on 2 publication(s) in Google Scholar
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.

Biological Activity
Description
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].

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.

RT-PCR
Reverse transcription technology uses RNA as a template to synthesize DNA. RT-PCR is simple, specific and sensitive, and can be used to detect gene expression levels and expression differences in cells; detect RNA virus content; clone cDNA sequences of specific genes.
-
RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.

Naïve CD4+ T-cell subset differentiation/polarization
Naïve CD4+ T-cell subset differentiation/polarization is an in vitro assay in which purified naïve CD4+ T cells are activated through TCR and CD28 costimulation and cultured with defined cytokines and neutralizing antibodies to generate Th0, Th1, Th2, Th17, or induced Treg-like populations. Differentiation is detected by subset-associated cytokines and transcription factors: IFN-γ/T-bet for Th1, IL-4/GATA3 for Th2, IL-17A/RORγt for Th17, and Foxp3 for induced Treg cells. The assay readout is usually generated by intracellular cytokine staining after restimulation, transcription-factor staining by flow cytometry, ELISA of secreted cytokines, or gene-expression analysis. The result reflects cytokine-directed lineage commitment or polarization rather than antigen-specific immune protection by itself.

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co

Real Time qPCR (Q-PCR)
Real-time quantitative PCR (qPCR) quantifies an amplifiable nucleic-acid target by monitoring fluorescence during PCR cycling rather than measuring product only after amplification. The increase in fluorescence tracks accumulation of PCR product, and the quantification cycle (Cq; historically also Ct/CP) is related to the initial amount of target: samples containing more starting target generally reach the defined fluorescence threshold in fewer cycles.
