Abstract

Aim: Direct oral anticoagulants (DOACs) are good alternatives to conventional medical regimens for the treatment and prevention of thromboembolism. Apixaban is one of the more popular variations of these newly developed drugs. Aside from its anticoagulant potential, possible cellular effects remain a topic for future studies. The object of this study was to investigate the possible antiangiogenic effects of apixaban in the chorioallantoic membrane (CAM) model.

Method: Drug pellets were prepared at 10-4, 10-5, and 10-6 M concentrations of apixaban and were placed in the chorioallantoic membrane on the fourth day of egg incubation. On the eighth day, all vascular densities of the membranes were compared with a 10-6 M concentration of bevacizumab, which is a known monoclonal, humanized, vascular endothelial growth-factor inhibitor.

Results: We find that a 10-4 M concentration of apixaban has strong antiangiogenic potential similar to that of bevacizumab. However, there was moderate antiangiogenic potential at a lower dose of apixaban (10-5 M, 10-6 M). A comparison of the higher doses of antiangiogenic potential (10-4 M concentration) with lower doses of apixaban (10-5 M, 10-6 M) revealed significant statistical differences (p < 0.05).

Conclusion: Our results indicate that a high dose of apixaban has strong antiangiogenic potential. The exact mechanism of this effect remains unknown. These pilot results should be confirmed with further studies to obtain an updated look at DOACs.

Apıxaban'ın Doza Bağlı Antianjiyojenik Potansiyeli: Deneysel Bir Bakış

Abstract

Amaç: Direkt oral antikoagülanlar (DOAK'lar), tromboembolizmin tedavisi ve önlenmesi için geleneksel tıbbi rejimlere iyi alternatiflerdir. Apixaban, bu yeni geliştirilen ilaçların daha popüler varyasyonlarından biridir. Antikoagülan potansiyelinin yanı sıra, olası hücresel etkiler gelecekteki çalışmaların konusu olmaya devam etmektedir. Bu çalışmanın amacı, korioallantoik membran (CAM) modelinde apiksaban'ın olası antianjiyogenik etkilerini araştırmaktı.

Yöntem: Apixaban'ın 10-4, 10-5 ve 10-6 M konsantrasyonlarında ilaç peletleri hazırlandı ve yumurta inkübasyonunun dördüncü gününde korioallantoik membrana yerleştirildi. Sekizinci günde, membranların tüm vasküler yoğunlukları, bilinen bir monoklonal, insanlaştırılmış, vasküler endotelyal büyüme faktörü inhibitörü olan 10-6 M'lik bir bevacizumab konsantrasyonu ile karşılaştırıldı.

Bulgular: 10-4 M apiksaban konsantrasyonunun, bevacizumabınkine benzer güçlü bir antianjiyogenik potansiyele sahip olduğunu bulduk. Bununla birlikte, daha düşük bir apiksaban dozunda (10-5 M, 10-6 M) orta düzeyde antianjiyogenik potansiyel vardı. Daha yüksek antianjiyogenik potansiyel dozlarının (10-4 M konsantrasyon) daha düşük dozlarda apiksaban (10-5 M, 10-6 M) ile karşılaştırılması, önemli istatistiksel farklılıklar ortaya çıkardı (p <0.05).

Sonuç: Sonuçlarımız, yüksek doz apiksaban'ın güçlü antianjiyogenik potansiyele sahip olduğunu göstermektedir. Bu etkinin kesin mekanizması bilinmemektedir. Bu pilot sonuçlar, DOAK'lara yeni bir bakış elde etmek için daha ileri çalışmalarla doğrulanmalıdır.
