Alpha-terpineol is a monoterpene alcohol with anti-tumor activity against different tumor cell lines (lung, breast, leukemias and colorectal) through blockage of NF-kB expression, which play an important role in tumor cells growth.

Evaluate the antitumor activity of alpha-terpineol in murine Sarcoma 180 cell line Methods For the tests, different cytotoxic and genotoxic assays were used, including Trypan blue, cytokinesis-blocked micronucleus assay, comet assay, agarose gel DNA fragmentation, flow cytometry and cell viability using fluorescence. Ascitic fluid cells from sarcoma 180 were obtained from Mus musculus peritoneal cavity and Alpha-terpineol was tested at 100, 250 and 500 μg/mL. Doxorubicin and Cisplatin were used as positive controls.

Cytotoxic effects of alpha-terpineol were found in all concentrations tested, reducing cell viability in 50.9; 38.53; 30.82% at 100, 250 and 500 μg/mL, respectively. read more Alpha-terpineol induced genotoxic effects due to DNA fragmentation (increased frequency and index of damage), and was clastogenic by increased micronuclei formation, nucleoplasmic bridges and nuclear buds. DNA fragmentation and increased cell death indicated that alpha-terpineol can cause early, late, and necrotic apoptosis.

Our data indicate that alpha-terpineol has antitumor activity revealed by cytogenetic mechanisms and / or loss of cell membrane integrity.

Neurokinin-1 receptor antagonists are playing a major advance in chemotherapy-induced nausea and vomiting (CINV) as powerful prophylactic agents. Therefore, it is significant to find the association between risk factors of patients and CINV so as to adjust the anti-emetic regimens.

To evaluate the role of neurokinin-1 receptor (NK-1R) antagonist in preventing chemotherapy-induced vomiting in the acute and delayed phases following first cycle of treatment.

145 adult patients with various cancers were recruited in Shanghai Changhai Hospital between September 2017 to November 2017, receiving dual or triple antiemetics.

NK-1R antagonist combined with dexamethasone, 5-HT3R antagonist could effectively control delayed-vomiting in patients after Cycle 1 chemotherapy treatment (4.1% VS 15.6%, P = 0.041<; 0.05). This study also showed that a history of motion sickness was a predictor of chemotherapy-induced vomiting (CINV) (P = 0.023 <; 0.05). In delayed phase a low consumption of alcohol and history of CIV for males were also significantly associated with CINV (P = 0.036 <; 0.05 and P = 0.002 <; 0.05 respectively).

In this study, we found that triple anti-emetic regimen with NK-1R antagonist could effectively prevent the delayed- vomiting than dual agents. Moreover, some risk factors were observed to be associated with CINV in the delayed phase.

Cancer accounts for several deaths each year. There are multiple FDA approved drugs for cancer treatments. Due to the severe side effects and multiple drug resistance, the current drug therapies become ineffective. So, the newer moieties with fewer toxic effects are necessary for the development.

The mechanism of indole derivatives as anti-cancer agents with their major target is explored in detail in this article.

Recent advances and mechanism of indole derivatives as anti-cancer agents are reviewed. This review suggests a detailed explanation of multiple mechanisms of action of various indole derivatives cell cycle arrest, aromatase inhibitor estrogen receptor regulator, tubulin inhibitor, a tyrosine kinase inhibitor, topoisomerase inhibitors, NFkB/PI3/Akt/mTOR pathway inhibitors, through which these derivatives have shown promising anti-cancer potential.

A full literature review showed that the indole derivatives are associated with the properties of inducing apoptosis, aromatase inhibition, regulation of estrogen receptor and inhibition of tyrosine kinase, tubulin assembly, NFkB/PI3/Akt/mTOR pathway, and HDACs. These derivatives have shown significant activity against cancer cell lines.

Indole derivatives seem to be important in cancer via acting through various mechanisms. This review has shown that the indole derivatives can further be explored for the betterment of cancer treatment, and to discover the hidden potential of indole derivatives.

Multiple myeloma (MM) is malignant hematologic disorder and the second most common blood cancer. Interleukin-6 (IL-6) has been identified as a crucial factor for proliferation and survival of MM cells and the overexpression of IL-6 receptor is being studied as a molecular target for therapeutic and diagnostic use in myelomas and other comorbidities. Tocilizumab is a humanized monoclonal antibody that binds IL-6R. <p >Objective We aim to label and evaluate Fab(Tocilizumab) with 99mTechnetium or Cy7 as potential MM imaging agents.

IL-6R distribution was analyzed by laser confocal microscopy (LCM) in MM cell lines. Fab(Tocilizumab) were produced by digestion of Tocilizumab with papain for 24 h at 37 °C, derivatized with NHS-HYNIC-Tfa and radiolabeled with 99mTc. Radiochemical stability and in vitro cell assays were evaluated. Biodistribution and SPECT/CT were performed. Also, Fab(Tocilizumab) was labeled with Cy7 for in vivo fluorescence imaging up to 72 h.

LCM analysis demonstrates IL-6R distributio fluorescent version could be used for tissue sample evaluation and to guide the surgical excision if necessary.
The development of cancer stem-like cells (CSCs) is one of the main causes of ovarian cancer tolerance to radiotherapy. Autophagy is an adaptive process by which cells repair damage due to radiation. As a metabolite of riboflavin, lumiflavin can enhance the chemotherapeutic effects of cisplatin on ovarian cancer CSCs.

This study aimed to investigate the synergistic effects of lumiflavin and ionising radiation on ovarian cancer CSCs and explore the association of this metabolite with autophagy.

CSCs of human ovarian cancer cell lines HO8910 were treated with lumiflavin and rapamycin and then subjected to irradiation at a cumulative dose of 8 Gy. Cell proliferation ability, clonal formation ability, apoptosis rate, autophagy changes and autophagy-related protein changes were detected.

Lumiflavin and ionising radiation synergistically reduced cell vitality and clone formation and increased the apoptosis of CSCs compared with irradiation alone. In addition, ionising radiation increased autophagy and the expression of associated proteins, whereas lumiflavin reduced those changes in autophagy progression.
