Current Landscape of Therapeutics for the Management of Hypertension - A Review

Exploring hypertension-linked diseases: a comprehensive review of innovative drug combinations with enhanced therapeutic potential

Hypertension, a prevalent cardiovascular condition affecting a substantial portion of the global population, remains a formidable health challenge associated with a multitude of complications. This review article provides a comprehensive examination of hypertension, its various complications, and the emergence of a novel management technique that shows promising potential in transforming the therapeutic landscape. Over the years, conventional treatment approaches, encompassing lifestyle modifications, dietary interventions, and pharmacotherapy, have been the mainstay in managing hypertension. However, these strategies fall short in achieving optimal blood pressure control and preventing complications in a significant number of patients. Consequently, the medical community has ventured into exploring innovative management techniques to tackle this unmet medical need. The focal point of this review centers on the emergence of a new management technique for hypertension that exhibits promise in preclinical and clinical studies. The latest research findings shed light on the efficacy and safety of this innovative approach, which encompasses pharmaceutical agents, medical devices, and non-invasive interventions. Through critical analysis and discussion, we explore the potential impact of these novel strategies on hypertension management and patient outcomes. In conclusion, this review article provides a comprehensive overview of hypertension, its complications, and the promising emergence of innovative management techniques. By acknowledging the complexity of hypertension and the potential of new therapeutic avenues, we aspire to pave the way for improved patient care, enhanced quality of life, and ultimately, the mitigation of hypertension-related morbidity and mortality.

From Sea to Lab: Angiotensin I-Converting Enzyme Inhibition by Marine Peptides-Mechanisms and Applications

To reveal potent ACE inhibitors, researchers screen various bioactive peptides from several sources, and more attention has been given to aquatic sources. This review summarizes the recent research achievements on marine peptides with ACE-inhibitory action and application. Marine peptides are considered excellent bioactives due to their large structural diversity and unusual bioactivities. The mechanisms by which these marine peptides inhibit ACE include competitive binding to ACEs' active site, interfering with ACE conformational changes, and avoiding the identification of substrates. The unique 3D attributes of marine peptides confer inhibition advantages toward ACE activity. Because IC50 values of marine peptides' interaction with ACE are low, structure-based research assumes that the interaction between ACE and peptides increased the therapeutic application. Numerous studies on marine peptides focused on the sustainable extraction of ACE-inhibitory peptides produced from several fish, mollusks, algae, and sponges. Meanwhile, their potential applications and medical benefits are worth investigating and considering. Due to these peptides exhibiting antioxidant, antihypertensive, and even antimicrobial properties simultaneously, their therapeutic potential for cardiovascular disease and other illnesses only increases. In addition, as marine peptides show better pharmacological benefits, they have increased absorption rates and low toxicity and could perhaps be modified for better stability and bioefficacy. Biotechnological advances in peptide synthesis and formulation have greatly facilitated the generation of peptide-based ACE inhibitors from marine sources, which subsequently offer new treatment models. This article gives a complete assessment of the present state of knowledge about marine organism peptides as ACE inhibitors. In addition, it emphasizes the relevance of additional investigation into their mechanisms of action, the optimization of manufacturing processes, and assessment in in vivo, preclinical, and clinical settings, underlining the urgency and value of this study. Using marine peptides for ACE inhibition not only broadens the repertory of bioactive compounds but also shows promise for tackling the global health burden caused by cardiovascular diseases.

Antihypertensive Property of Celery: A Narrative Review on Current Knowledge

Background

The incidence of hypertension is increasing significantly on a global scale, and it is considered the leading cause of heart disease and death. Despite the availability of hypotensive drugs, they have many side effects that decrease adherence to treatments and lead to uncontrolled blood pressure. Studies have revealed that celery contains bioactive compounds that oppose hypotensive effect.

Methods

A thorough literature review was conducted using Scopus, PubMed, and Google Scholar databases. To identify relevant studies on the topic, our search strategy employed keywords such as "celery," "Apium gravenols L," "hypertension," "high blood pressure," "apigenin," "antihypertensive," and "hypotensive." The search was limited to articles published between January 2013 and December 2023. The inclusion criteria were original research articles that involved both animal and human subjects, published in English, and reported results applicable to the subject of this review. Review articles or articles in the form of theses or books were excluded.

Results

The available evidence revealed that celery enhances blood pressure parameters. Clinical trials clarified that celery possesses its effect through many bioactive compounds, specifically 3-n-butylphthalide and apigenin. Based on animal and human studies, celery seems to elicit blood pressure regulation mainly by the vasodilatory, diuretic, and calcium channel-blocking properties. Furthermore, celery seed extract seems to exert a bradycardia effect.

Conclusion

The current literature review showed a considerable number of studies on the hypertensive models, which confirmed that celery and its extracts are effective hypotensive agents. Some limitations in comparing published data should be considered, including differences in doses, extracts, species of celery, and administration form.

Cisplatin-based Liposomal Nanocarriers for Drug Delivery in Lung Cancer Therapy: Recent Progress and Future Outlooks

In order to improve the treatment of lung cancer, this paper looks at the development of cisplatinbased liposomal nanocarriers. It focuses on addressing the drawbacks of conventional cisplatin therapy, including systemic toxicity, inadequate tumor targeting, and drug resistance. Liposomes, or spherical lipid vesicles, offer a potentially effective way to encapsulate cisplatin, enhancing its transport and minimizing harmful effects on healthy tissues. The article discusses many liposomal cisplatin formulations, including pH-sensitive liposomes, sterically stabilized liposomes, and liposomes coupled with specific ligands like EGFR antibodies. These novel formulations show promise in reducing cisplatin resistance, optimizing pharmacokinetics, and boosting therapeutic results in the two in vitro and in vivo models. They also take advantage of the Enhanced Permeability and Retention (EPR) effect in the direction of improved tumor accumulation. The study highlights the need for more investigation to move these liposomal formulations from experimental to clinical settings, highlighting their potential to offer less harmful and more effective cancer therapy alternatives.
