Một chất ức chế phân tử nhỏ Bcl-2 mới 4-(3-methoxy-phenylsulfannyl)-7-nitro-benzofurazan-3-oxide (MNB) gây ra hiện tượng apoptosis trong các tế bào leukemia
Tóm tắt
Một chất ức chế phân tử nhỏ mới, 4-(3-methoxy-phenylsulfannyl)-7-nitro-benzofurazan-3-oxide (MNB), cạnh tranh với peptide Bak BH3 để gắn vào protein Bcl-2 với độ ái lực gắn kết IC50 = 0.70 μM, được đánh giá bằng cách thử nghiệm gắn kết dựa trên phân cực huỳnh quang. Tế bào HL-60 có mức độ biểu hiện Bcl-2 cao nhất trong số các dòng tế bào được kiểm tra. Khi được điều trị với 5 μM MNB trong 6 giờ, 85% tế bào HL-60 đã được phát hiện là trải qua hiện tượng apoptosis. Chất ức chế pan-caspase, Z-VAD-FMK, ngăn chặn hiện tượng apoptosis do MNB gây ra trong tế bào HL-60. Sự hoạt hóa của các caspase-2, caspase-3, caspase-7, caspase-8, caspase-9 và PARP đã được quan sát thấy từ sớm, từ 4 đến 6 giờ điều trị MNB. Ngoài ra, đã được xác nhận rằng chất ức chế đặc hiệu caspase-3, Z-DEVD-FMK, ngăn chặn sự hoạt hóa của caspase-8 trong tế bào HL-60 được điều trị bằng MNB. Điều trị bằng MNB không làm thay đổi mức độ biểu hiện Bcl-2 hoặc Bax trong tế bào HL-60, nhưng gây ra sự cắt ngang của Bid. Các thí nghiệm tiếp theo đã chứng minh rằng MNB ức chế sự hợp dimer của Bcl-2 với Bax hoặc Bid, giảm tiềm năng màng ty thể (ΔΨmt), và gây ra sự phóng thích cytochrome c từ ty thể trong tế bào HL-60. Những kết quả này gợi ý rằng MNB gây ra hiện tượng apoptosis trong HL-60 bằng cách ức chế sự hợp dimer của Bcl-2 với các thành viên Bcl-2 thúc đẩy apoptosis, dẫn đến việc giảm tiềm năng màng ty thể và sự phóng thích cytochrome c, sự hoạt hóa của các caspase và PARP; đây là một quá trình phụ thuộc vào caspase mà trong đó sự hoạt hóa của caspase-8 phụ thuộc vào con đường truyền tín hiệu apoptosis của ty thể. MNB kéo dài tuổi thọ cho chuột mang HL-60, giết chết mạnh mẽ các tế bào AML và ALL tươi, chỉ ra rằng nó có tiềm năng được phát triển để điều trị bệnh bạch cầu.
