BMS-599626 inhibits tumor cell proliferation and has the potential to increase tumor BMS-599626 inhibits tumor cell proliferation and has the potential to increase tumor response to radiotherapy.

CMP3a is a NEK2 kinase inhibitor. CMP3a efficiently attenuated GBM growth in a mouse model and exhibited a synergistic effect with radiotherapy. Targeting NEK2 attenuates glioblastoma growth and radioresistance by destabilizing histone methyltransferase E

L-778123 is an inhibitor of FPTase and GGPTase-I. The combination of L-778123 and radiotherapy at dose level 1 showed acceptable toxicity in patients with locally advanced pancreatic cancer.

GLYN, a nitric oxide donor, acts by enhancing the therapeutic efficacy of chemotherapy and radiotherapy.

NLCQ-1 is a novel weak DNA-intercalative bioreductive compound. NLCQ-1 exhibited a C50 of 44 microM. NLCQ-1 demonstrated significant hypoxic selectivity in several rodent (V79, EMT6, SCCVII) or human (A549, OVCAR-3) tumor cell lines. Its potency as a hypo

1. β,β-Dimethylacrylshikonin (Dimethylacrylshikonin) is a promising agent for developing an improved strategy for radiotherapy against tumors. (a) Injection of Dimethylacrylshikonin combined with IR treatment significantly suppressed tumor growth of the HCT-116 xenograft. (b) Dimethylacrylshikonin significantly suppressed the growth of H(22) transplantable hepatoma, and induced the activation of caspase-3 . (c) Dimethylacrylshikonin inhibited growth of gastric cancer SGC-791 cells by inducing ERK signaling pathway. 2. Dimethylacrylshikonin inhibits the proliferation of MCF-7 cells in vitro by inducing apoptosis through the downregulation of Bcl-2, upregulation of Bax and partial inactivation of the NF-κB pathway.

DNA-PK-IN-6, a robust DNA-PK inhibitor, effectively hampers the activity of DNA-PKcs, thereby significantly impairing the DNA repair mechanism in tumors and instigating apoptosis in cells. Additionally, DNA-PK-IN-6 amplifies the responsiveness of tumor tissues to radiotherapy, overcomes the challenge of drug resistance, and augments its inhibitory impact on a diverse range of solid and hematological tumors[1].

DNA-PK-IN-3 is a highly potent inhibitor of DNA-PK that exerts a synergistic effect with radiotherapy and chemotherapy, enhancing therapeutic outcomes and significantly inhibiting tumor growth.
