Design and synthesis of isatin derivative payloaded peptide-drug conjugate as tubulin inhibitor against colorectal cancer.

A series of isatin derivatives which could inhibit colorectal cancer (CRC) were synthesized. Among those compounds, 5B exhibited good inhibitory activity of CRC through the inhibition of tubulin expression, inducing apoptosis, and causing G2/M phase cell cycle arrest pathway, which suggested that 5B could be a potential tubulin inhibitor. Based on that, a novel peptide-drug conjugate (PDC), which employed the CRC cells related receptor CD44 ligand peptide A6 coupling to 5B to accomplish A6-5B.

Drug combinations of camptothecin derivatives promote the antitumor properties.

Camptothecin (CPT) derivatives are widely used as small molecule chemotherapeutic agents and have demonstrated efficacy in the treatment of diverse solid tumors. A variety of derivatives have been developed to resolve the drawbacks of poor water solubility, high toxicity and rapid hydrolysis in vivo. However, the obstacles, such as acquired resistance and toxicity, still exist.

Cyclodextrin-based metal-organic frameworks transforming drug delivery.

Synthesis and mechanism of action of new purine derivatives against triple negative breast cancer.

Triple negative breast cancer (TNBC) is considered to be the most difficult subtype of breast cancer to treat because of its extremely prone to metastasis and the lack of targeted therapy drugs. New purine derivatives were synthesized and evaluated in a series of kinases and cell lines. The most active compounds 3g and 3j were selected based on their antiproliferative activities, then their pharmaceutical activity and mechanism in MDA-MB-231 cells were analyzed.

Podophyllotoxin-loaded PEGylated E-selectin peptide conjugate targeted cancer site to enhance tumor inhibition and reduce side effect.

E-selectin, which is highly expressed in vascular endothelial cells near tumor and get involved in the all tumor growth steps: occurrence, proliferation and metastasis, is considered as a promise targeted protein for antitumor drug discovery. Herein, we would like to report the design, preparation and the anticancer evaluation of the peptide-PEG-podophyllotoxin conjugate(PEG-Pep-PODO), in which the short peptide (CIELLQAR) was used as the E-selectin ligand for the targeting purpose and the PEG portion the molecule got the conjugate self-assembled to form a water soluble nanoparticle. In vitro release study showed that the conjugated and entrapped PODO could be released simultaneously in the presence of GSH (highly expressed in tumor environmental conditions) and the GSH would catalyze the break of the disufur bond which linked of the PODO and the peptide-PEG portion of the conjugate.

Development of 10-Hydroxycamptothecin-crizotinib conjugate based on the synergistic effect on lung cancer cells.

The effect of the combination of 10-Hydroxycamptothecin (HCPT) and crizotinib (CRI) on EGFR- and KRAS-mutant lung cancer cells was investigated and the conjugates of the two drugs were synthesised. HCPT combined with CRI synergistically inhibited the cell growth and proliferation of H1975, HCC827, and H460 without aggravating adverse effect on the normal cells. The combination synergistically enhanced the cell apoptosis rate through releasing Cyto-C by activation of Bcl-2 family-mediated mitochondrial signalling, which was associate with inactivating of EGFR related downstream signalling pathways including AKT, ERK, JNK, and p38 MAPK.

Selenium substituted axitinib reduces axitinib side effects and maintains its anti-renal tumor activity.

Axitinib is a potent vascular endothelial growth factor receptor (VEGFR) inhibitor, which has a strong inhibitory effect on the three isoforms of VEGFR 1-3.

Selenium compounds are broadly reported to have a good protective effect on cardiovascular disease, inflammation, infection, and immune function.

Molecular mechanisms in Alzheimer's disease and related potential treatments such as structural target convergence of antibodies and simple organic molecules.

The amyloid cascade is the most frequently accepted hypothesis of Alzheimer's Disease (AD). According to this hypothesis, the formation of plaques precedes the appearance of fibrillary tangles. Therapeutic agents able to inhibit the formation of plaques are therefore considered as potential disease-modifying treatments (DMT) that could prevent or limit the progression of AD.
