Abstract
Breast cancer became the most diagnosed cancer in the world in 2020. Chemotherapy is still the leading clinical strategy in breast cancer treatment, followed by hormone therapy (mostly used in hormone receptor-positive types). However, with our ever-expanding knowledge of signaling pathways in cancer biology, new molecular targets are identified for potential novel molecularly targeted drugs in breast cancer treatment. While this has resulted in the approval of a few molecularly targeted drugs by the FDA (including drugs targeting immune checkpoints), a wide array of signaling pathways seem to be still underexplored. Also, while combinatorial treatments have become common practice in clinics, the majority of these approaches seem to combine molecularly targeted drugs with chemotherapeutic agents. In this manuscript, we start by analyzing the list of FDA-approved molecularly targeted drugs for breast cancer to evaluate where molecular targeting stands in breast cancer treatment today. We will then provide an overview of other options currently under clinical trial or being investigated in pre-clinical studies.

Abstract
Isoxazoles and isoxazolines are five-membered heterocyclic molecules containing nitrogen and oxygen. Isoxazole and isoxazoline are the most popular heterocyclic compounds for developing novel drug candidates. Over 80 molecules with a broad range of bioactivities, including antitumor, antibacterial, anti-inflammatory, antidiabetic, cardiovascular, and other activities, were reviewed. A review of recent studies on the use of isoxazoles and isoxazolines moiety derivative activities for natural products is presented here, focusing on the parameters that affect the bioactivity of these compounds.

Abstract
<b>Background and Objective:</b> The AL22 strain was isolated from the rhizosphere soil of <i>Alpinia galanga</i> (L.) Willd (Zingiberaceae) and identified as <i>Microbispora</i> sp., by analysing its morphology, chemotaxonomy and 16S rDNA sequence. Previous studies demonstrated the bactericidal effects of its crude extract against <i>Bacillus cereus</i>, <i>Bacillus subtilis</i>, <i>Staphylococcus aureus</i> and methicillin-resistant <i>Staphylococcus aureus</i>. The present study aimed to isolate the major compounds and evaluate their biological properties. <b>Materials and Methods:</b> Silica gel column chromatography and thin-layer chromatography were used for the purification and identification of 3,4-dihydro-lactucin (compound <b>1</b>) and umbelliferone (compound <b>2</b>) by NMR and mass spectrometry, respectively. Antibacterial and anticancer activities were carried out. <b>Results:</b> The bioassay studies illustrated that compound <b>1</b> had antibacterial activity against gram-positive bacteria, with its minimum inhibitory concentration and minimum bactericidal concentration of 16-32 and 64-128 μg mL<sup></sup><sup>1</sup>, respectively. The crude extract and purified compounds showed weak cytotoxic activity on the L929 and Vero cells with IC<sub>50</sub> values >512.00 μg mL<sup></sup><sup>1</sup>. The cytotoxicity of compound <b>1</b> was observed in the MDA-MB-231 and HeLa cells with IC<sub>50</sub> values of 37.62 and 75.34 μg mL<sup></sup><sup>1</sup>, respectively, while its IC<sub>50</sub> value against the HepG2 cells was 456.67 μg mL<sup></sup><sup>1</sup>. <b>Conclusion:</b> These findings showed that compound <b>1</b> of <i>Microbispora</i> sp., AL22 exhibited antibacterial and anticancer activities. Extensive studies on 3,4-dihydro-lactucin could lead to the development of beneficial approaches for managing bacterial infections and cancer.

[PMID: 32565961 PMCID: PMC7286138 DOI: 10.3892/ol.2020.11546] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Accepted: 03/05/2020] [Indexed: 12/21/2022] Open
Abstract
Dihydromyricetin (DMY) is a novel natural drug with antitumor activity against some cancer cells without obvious toxicity. Previously, its apoptotic effect on human choriocarcinoma was detected. The present study further investigated the therapeutic potential of DMY as a new drug for the treatment of choriocarcinoma, as well as its anti-proliferative effect and mechanism of action. The short-term proliferation of JAR cells was determined by MTT assay, whereas the effect of DMY on long-term cell proliferation was determined by colony forming assay. Flow cytometry was used to detect changes in the cell cycle. Furthermore, western blotting was used to detect the expression levels of proliferation-associated proteins such as cyclin A1, cyclin D1, SMAD3 and SMAD4. Reverse transcription-quantitative PCR (RT-qPCR) was used to quantify mRNA expression levels. The results indicated that DMY inhibited short and long-term proliferation of JAR cells in a concentration-dependent manner. Flow cytometry demonstrated S/G2/M cell cycle arrest, and western blotting revealed the downregulation of SMAD3, SMAD4, cyclin A1 and cyclin D1 expression levels. The results of RT-qPCR and western blotting were consistent. Overall, the findings of the present study suggest that DMY inhibits the proliferation of human choriocarcinoma JAR cells, potentially through cell cycle arrest via the downregulation of cyclin A1, cyclin D1, SMAD3 and SMAD4 expression levels.
