Selective Cav1.3 inhibition promotes survival of transplanted dopaminergic neurons via the CaMKII-p65-p53 pathway. (PubMed, Stem Cell Reports) - "Cav1.3 inhibitors including isradipine and cp-PYT significantly reduced apoptosis and improved mDAN survival in both interferon gamma (IFN-γ)- and tumor necrosis factor alpha (TNF-α)-induced inflammatory models, as well as in the 6-OHDA-induced toxic model in vitro...Moreover, we showed that cp-PYT treatment enhanced mDAN survival while reducing mature graft volume post-transplantation. Therefore, Cav1.3 inhibition may represent a clinically relevant strategy to enhance the survival of human pluripotent stem cell (hPSC)-derived mDANs in cell therapy for PD."

Impact of antihypertensive treatment on cardiovascular event reduction in patients with asymptomatic carotid artery stenosis: a systematic review and meta-analysis. (PubMed, Pan Afr Med J) - "The results reported that enalapril and fosinopril demonstrated dual benefits in blood pressure (BP) reduction and vascular remodeling, though meta-analysis showed statistically insignificant improvements in regional cerebral blood flow (CI: -0.84, 6.08, P = 0.14, I2= 94%). Similarly, isradipine, lacidipine, and amlodipine improved carotid hemodynamics and cerebral perfusion, with meta-analysis favoring calcium channel blocker intervention for blood pressure management (CI: -3.25 to 7.64, P = 0.43)...Moreover, beta-blockers showed specific benefits, with metoprolol improving plaque echogenicity (57.3 ± 16.8 vs. 51.8 ± 20.0, p = 0.006) and reducing cardiovascular events (17% vs. 37% placebo, p = 0.011), while labetalol effectively managed post-endarterectomy hypertension. In conclusion, antihypertensive treatments showed varying effectiveness in cardiovascular event reduction and improvements in vessel measures."

Therapeutic innovation through drug repurposing: A multidimensional approach toward treating Parkinson's disease. (PubMed, Bioorg Chem) - "Ongoing research is actively investigating several repurposed drugs originally intended for different conditions, including anti-hypertensives (isradipine, dexmedetomidine), anti-asthmatics (montelukast), phosphodiesterase5 inhibitors (sildenafil), antimicrobials (rifaximin), and various CNS-active agents (aripiprazole, escitalopram, paroxetine, venlafaxine, duloxetine, caffeine). While drug repurposing holds considerable promise, comprehensive preclinical and clinical studies are essential to validate these candidates for PD-specific therapeutic applications. This review aims to provide an in-depth overview of PD, encompassing its pathological and molecular characteristics, and to critically evaluate the current landscape of drug repurposing strategies to develop effective therapies for PD."

Therapeutic Potential of Calcium Channel Blockers in Neuropsychiatric, Endocrine and Pain Disorders. (PubMed, Cells) - "In neuropsychiatry, nimodipine and isradipine, both L-type CCBs, show mood-stabilizing and neuroprotective effects, with possible benefits in depression, bipolar disorder, and schizophrenia. In endocrinology, verapamil, a non-dihydropyridine L-type blocker, has been associated with the preservation of pancreatic β-cell function and reduced insulin dependence in diabetes...However, their broader use is limited by challenges in central nervous system (CNS) penetration, off-target effects, and heterogeneous trial outcomes. Future research should focus on pharmacogenetic stratification, novel delivery platforms, and combination strategies to optimize repurposing of CCBs across disciplines."

L-type calcium channel blockade attenuates cue-induced cocaine-seeking in female rats. (PubMed, Behav Brain Res) - "Following a 10-day cocaine self-administration and a 14-day forced abstinence period, the rats were tested for cue-induced cocaine-seeking after receiving systemic administration of isradipine, a non-selective LTCC inhibitor (0.0mg/kg, 0.1mg/kg, 0.4mg/kg, or 1.2mg/kg, i.p.)...These results highlight the translational potential of LTCCs as a therapeutic agent to reduce relapse risk in cocaine-dependent individuals. This study underscores the importance of considering sex-specific mechanisms in addiction treatment and calls for further research into LTCCs as a target for relapse prevention."

SINGLE-MICROGLIA TRANSCRIPTOMIC TRANSITION NETWORK-BASED PREDICTION AND REAL-WORLD PATIENT DATA VALIDATION IDENTIFIES KETOROLAC AS A REPURPOSABLE DRUG FOR ALZHEIMER'S DISEASE (ADPD 2025) - "We presented a network-based drug repurposing prediction by specifically blocking transition networks from neuroinflammation like microglia (NIM) to non-NIM and we identified a set of highly repurposable drugs (i.e., ketorolac, diflunisal, bezafibrate, and isradipine) for potential treatment of AD. Using two independent real-world patient databases (MarketScan [172 million insured individuals] and INSIGHT Clinical Research Network [15 million patients]), we identified that usage of Ketorolac was associated with reduced AD incidence in both MarketScan (hazard ratio [HR] = 0.89) and INSIGHT (HR = 0.83) Clinical Research Network databases, mechanistically supported by Ketorolac-treated transcriptomic data from AD patient iPSC-derived microglia. Conclusions This study offers insights into the pathobiology of AD-relevant microglial subtypes and identifies Ketorolac as a potential anti-inflammatory treatment for AD."

Inactivation induced by pathogenic Cav1.3 L-type Ca2+-channel variants enhances sensitivity for dihydropyridine Ca2+ channel blockers. (PubMed, Br J Pharmacol) - "Mutations A749T and L271H induce pathogenic gating changes. Like wildtype, isradipine inhibition is strongly voltage-dependent. Our data explains their apparent higher drug sensitivity at a given negative voltage by the availability of more inactivated channels due to their more negative inactivation voltage range. Low nanomolar isradipine concentrations will only inhibit Cav1.3 channels in neurons during prolonged depolarized states without selectivity for mutant channels."

Bullous IgA Vasculitis: A Unique Presentation and Potential Marker of Severity (AAP-NCE 2024) - "She was started on lisinopril with as needed isradipine for hypertension.On day one of admission, she developed severe periumbilical pain, without evidence of intussusception on ultrasound, and was started on methylprednisolone...Her rash began improving on day four and she was discharged home on lisinopril, furosemide, and prednisolone... By being aware of this unique presentation of bullous IgA vasculitis, unnecessary skin biopsies can be avoided in patients who present with skin purpura consistent with IgA vasculitis that advances into bullae. Current evidence is nonconclusive regarding the link between severity of skin findings and renal involvement, however this unique case suggests these findings may be a useful predictor which can broaden our understanding with research into the severity of disease and skin findings on clinical presentation."

Genetic signatures stratify PwP into three subgroups with differing responses in two disease-modifying Phase 3 trials and indicate multiple disease biology pathways to Parkinson's Disease (MDS Congress 2024) - "WGS and pharmacokinetic data from two disease-modifying Phase 3 trials, where testing of isradipine (STEADY-PD3) or inosine/urate (SURE-PD3) did not show efficacy in early-stage PD, were modelled for treatment and exposure effects for multiple clinical outcomes in each of the 3 subgroups... Treatments that address the heterogeneity and complexity of PD are the most likely to benefit patients. We have identified a genetic signature, relevant to PD, that stratifies PwP into three subgroups. When applied to clinical data from two previously conducted Phase 3 clinical trials, it was evident that participants with differing genetic signatures responded differently to the trial therapeutic both within and between trials."

Targeting calciumopathy for neuroprotection: focus on calcium channels Cav1, Orai1 and P2X7. (PubMed, Cell Calcium) - "Thus, a recent CT tested whether isradipine, a blocker of the Cav1 subtype of voltage-operated calcium channels (VOCCs), exerted a benefit in patients with Parkinson's disease (PD); however, outcomes were negative...Thus, by targeting the three channels with a combination of three drug blockers we expect favorable changes in some of the pathogenic features of NDDs, namely (i) to mitigate Ca2+ entry into microglia; (ii) to decrease the Ca2+-dependent microglia activation; (iii) to decrease the sustained neuroinflammation; (iv) to decrease the uncontrolled Ca2+ entry into neurons; (v) to rescue vulnerable neurons from death; and (vi) to delay disease progression. In this review we discuss the arguments underlying our triad hypothesis in the sense that the combination of three repositioned medicines targeting Cav1, Orai1, and P2X7 calcium channels could boost neuroprotection and delay the progression of AD and other NDDs."

L-type calcium channel regulation of depression, anxiety and anhedonia-related behavioral phenotypes following chronic stress exposure. (PubMed, Neuropharmacology) - "In female and male rats, systemic administration of the LTCC blocker isradipine (0.4 mg/kg and 1.2 mg/kg, I.P.) attenuated the CUS-induced decrease in sucrose preference and reversed the CUS-induced decrease in open arm time...However, there were no significant differences in forced swim test immobility time between HCC and CUS exposed animals. Taken together, these data point to a role of LTCCs in the regulation of mood disorder-related behavioral phenotype responses to chronic stress exposure."
