The cyclic RGD peptide cilengitide is a potential cancer drug. Cilengitide is under investigation for the treatment of glioblastoma, where it may act by inhibiting angiogenesis, and influencing tumor invasion and proliferation.

Cilengitide is a new chemotherapeutic agent that was shown to be effective against renal cell cancer in vitro. Cilengitide inhibits the polymerase chain reaction, arresting the growth of cells. It has minimal toxicity and natural compounds, which make it a promising drug for the treatment of human cancers. Cilengitide binds to integrin receptors on malignant brain cells and inhibits their ability to migrate, inducing apoptosis. This drug also inhibits the production of chemoattractant protein and can be used as an adjuvant therapy for radiation and antibiotic-resistant strains of bacteria.

RGD肽-说明

RGD肽是指含有由Arg-Gly-Asp三个氨基酸组成的序列多肽，有直线肽和环肽之分。它们是许多细胞外基质蛋白（如VN、FN、FGN、胶原等）等最小识别短肽序列。

研究发现，RGD序列肽具有广泛的生物活性，可用于心血管疾病、骨质疏松和炎症等疾病的治疗，还可以预防和治疗由细胞粘附异常而导致的肿瘤，尤其是发展性肿瘤的转移；另一方面，RGD 序列肽又可作为兴奋剂，促进损伤的器官与组织的再生、伤口的愈合等等，RGD作为某些整合素的受体，其选择性部分依赖于RGD的构象以及RGD周围的氨基酸残基。

为此，近几年，许多科技工作者合成了一系列RGD三肽、四肽、五肽等，还合成了RGD环肽、双线肽、RGD模拟肽等等。为了满足客户对各种RGD序列肽的需求，专肽生物提供最广泛的RGD序列肽库，以满足科研工作者对RGD肽的需求。

专肽生物提供各种RGD肽的现货，缩短科研工作者的项目时间，例如c(RGDfK)、c(RGDfC)、c(RADyK)、c(RGDyK)、c(RADfC)、环状多肽c(RGDfK)-巯基乙酸、c(RGDfK)-PEG2-巯基乙酸、Mpa-Ahx-c(RGDfK)、环状多肽c(RGDfK)-半胱氨酸、DOTA-c(RGDfK)、NOTA-c(RGDfK)、NOTA-c(RGDyK)、DOTA-c(RGDyK)、E[c(RGDfK)]2、E[c(RGDyK)]2、DDDDD-c(RGDfK)等等，具体可咨询销售人员。
