Cancer is a major global concern. Despite considerable advancements in cancer therapy and control, there are still large gaps and requirements for development. In recent years, various naturally occurring anticancer drugs have been derived from natural resources, such as alkaloids, glycosides, terpenes, terpenoids, flavones, and polyphenols.

Six pyridine analogs of (E)-3-(3-(1,2,3,4-tetrahydro-1,1,4,4,6-pentamethylnaphthalen-7-yl)-4-hydroxyphenyl)acrylic acid-or CD3254 (11)-in addition to two novel analogs of 1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-1H-benzo[d][1,2,3]triazole-5-carboxylic acid (CBt-PMN or 23) were prepared and evaluated for selective retinoid-X-receptor (RXR) agonism alongside bexarotene (1), an FDA-approved drug for cutaneous T-cell lymphoma (CTCL). Treatment with 1 often elicits side-effects by disrupting or provoking other RXR-dependent nuclear receptors and cellular pathways. All analogs were assessed through modeling for their ability to bind RXR and then evaluated in human colon and kidney cells employing an RXR-RXR mammalian-2-hybrid (M2H) system and in an RXRE-controlled transcriptional assay.

Although leukemia in the Japanese atomic bomb survivor data has long exhibited upward curvature, until recently this appeared not to be the case for solid cancer. It has been suggested that the recently observed upward curvature in the dose response for the Japanese atomic bomb survivor solid cancer mortality data may be accounted for by flattening of the dose response in the moderate dose range (0.3-0.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

Myeloid sarcoma (MS) is an extramedullary localization of immature granulocyte cells that can occur in association with acute myeloid leukemia (AML). Gastrointestinal involvement is relatively common in MS, but exclusive colonic localization is a rare occurrence. Here, we report on a 53-year-old male patient affected by AML developing a severe abdominal pain caused by intestinal perforation requiring surgical intervention.
