Rosavin exerts an antitumor role and inactivates the MAPK/ERK pathway in small-cell lung carcinoma .

This study attempts to explore the function and mechanism of action of rosavin in small-cell lung cancer (SCLC) . The viability and clone formation of SCLC cells were assessed using cell counting kit-8 and colony formation assays, respectively. Apoptosis and cell cycle were detected using flow cytometry and cell cycle analysis, respectively.

Redox-Active Azulene-based 2D Conjugated Covalent Organic Framework for Organic Memristors.

As a conjugated and unsymmetric building block composed of an electron-poor seven-membered sp carbon ring and an electron-rich five-membered carbon ring, azulene and its derivatives have been recognized as one of the most promising building blocks for novel electronic devices due to its intrinsic redox activity. By using 1,3,5-tris(4-aminophenyl)-benzene and azulene-1,3-dicarbaldehyde as the starting materials, an azulene(Azu)-based 2D conjugated covalent organic framework, COF-Azu, is prepared through liquid-liquid interface polymerization strategy for the first time. The as-fabricated Al/COF-Azu/indium tin oxide (ITO) memristor shows typical non-volatile resistive switching performance due to the electric filed induced intramolecular charge transfer effect.

Donor-acceptor-type poly[chalcogenoviologen--triphenylamine] for synaptic biomimicking and neuromorphic computing.

Polymer memristors are preeminent candidates for low-power edge computing paradigms. Poly[chalcogenoviologen--triphenylamine] (PCVTPA) has been synthesized by direct coupling of chalcogeno-viologen as electron acceptor and 4-(bromomethyl)-N-(4-(bromo-methyl)phenyl)-N-phenylaniline as electron donor. The introduction of chalcogen atoms (S, Se, Te) into viologen scaffolds can greatly improve electrical conductive, electrochemical, and electrochromic properties of the materials when compared with the conventional viologens.

US National Cancer Institute-China Collaborative Studies on Chinese Medicine and Cancer.

Since 2007, the US National Cancer Institute (NCI) Office of Cancer Complementary and Alternative Medicine (OCCAM), together with the Cancer Institute of the China Academy of Chinese Medical Sciences (CICACMS), institutes at China Academy of Sciences and Chinese Academy of Medical Sciences, have engaged in collaborations on Chinese medicine (CM) and cancer research. Through these collaborations, CM drugs and compounds have been studied at NCI labs. This paper summarizes the discoveries and progress on these research projects, exploring the aspects of cancer prevention, botanical drug mechanisms of action and component analysis/quality control (QC), and anticancer activity screening.

Fufang Kushen injection inhibits sarcoma growth and tumor-induced hyperalgesia via TRPV1 signaling pathways.

Cancer pain is a deleterious consequence of tumor growth and related inflammation. Opioids and anti-inflammatory drugs provide first line treatment for cancer pain, but both are limited by side effects. Fufang Kushen injection (FKI) is GMP produced, traditional Chinese medicine used alone or with chemotherapy to reduce cancer-associated pain.

Compound Kushen Injection suppresses human breast cancer stem-like cells by down-regulating the canonical Wnt/β-catenin pathway.

Background: Cancer stem cells (CSCs) play an important role in cancer initiation, relapse and metastasis. To date, no specific medicine has been found to target CSCs as they are resistant to most conventional therapies and proliferate indefinitely. Compound Kushen Injection (CKI) has been widely used for cancer patients with remarkable therapeutic effects in Chinese clinical settings for many years.
