Design, synthesis and biological evaluation of novel o-aminobenzamide derivatives as potential anti-gastric cancer agents in vitro and in vivo

Although gastric cancer has become a major public health problem, oral agents applied in clinics for gastric cancer therapy are scarce. Therefore, to explore new oral chemical entities with high efficiency and low toxicity, 41 o-aminobenzamide derivatives based on the scaffolds of MS-275 and SAHA were designed, synthesized, and evaluated for their anti-gastric cancer abilities in vitro and in vivo. Structure-activity relationships were discussed, leading to the identification of compounds F8 (IC50 = 0.28 μM against HGC-27 cell) and T9 (IC50 = 1.84 μM against HGC-27 cell) with improved cytotoxicity, anti-gastric cancer proliferation potency, induction of cell apoptosis and cell cycle arrest ability, inhibition of cell migration and invasion. What is worth mentioning is that compound F8 was more efficient and less toxic than the positive drug capecitabine in vivo on the HGC-27-xenograft model. Meanwhile, compound F8 exhibited suitable pharmacokinetic properties and less acute toxicity (LD50 > 1000 mg/kg). Besides, western blotting analysis, IHC analysis, differentially expressed proteins analysis and ABPP experiment indicated that compound F8 could modulate molecular pathways involved in apoptosis and cell cycle progression. Consequently, compound F8 is a strong candidate for the development of human gastric cancer therapy.

Design, synthesis and preliminary bioactivity evaluations of 8-hydroxyquinoline derivatives as matrix metalloproteinase (MMP) inhibitors

Matrix metalloproteinases (MMPs) play important roles in many diseases including cancer. With moderate metal-binding affinity, 8-hydroxyquinoline has gained much interest in current drug design and development. Specially, it has been reported that 8-hydroxyquinoline derivatives serve as MMP-2 inhibitors with micromolar IC50 values. In the current study, a series of 8-hydroxyquinoline derivatives were designed and synthesized as new MMP-2 and MMP-9 inhibitors. The most active compounds 5e and 5h not only displayed good inhibitory activities against MMP-2/9 with IC50 at submicromolar level, but also possessed potent anti-proliferative, anti-invasive and anti-angiogenesis activity in A549 cell line. Western blot also revealed that 5e and 5h down-regulate the expression of MMP-2 and MMP-9 in A549 cell line. Moreover, flow cytometry analysis indicated that compound 5e could promote apoptosis of A549 cells in vitro. Molecular docking analysis also revealed favorable binding modes of 5e in the active sites of MMP-2 and MMP-9.

Versatile probes for the selective detection of vicinal-dithiol-containing proteins: Design, synthesis, and application in living cells

Endogenous vicinal-dithiol-containing proteins (VDPs) that have two thiol groups close to each other in space play a significant importance in maintaining the cellular redox microenvironment. Approaches to identify VDPs mainly rely on monitoring the different concentration of monothiol and total thiol groups or on indirect labeling of vicinal thiols by using p-aminophenylarsenoxide (PAO). Our previous work has reported the direct labeling of VDPs with a highly selective receptor PAO analogue, which could realize fluorescence detection of VDPs directly in living cells. Herein, we developed a conjugated approach to expand detectable tags to nitrobenzoxadiazole (NBD), fluorescein, naphthalimide, and biotin for the synthesis of a series of probes. Different linkers have also been introduced toward conjugation of VTA2 with these functional tags. These synthesized flexible probes with various features will offer new tools for the potential identification and visualization of vicinal dithiols existing in different regions of VDPs in living cells. These probes are convenient tools for proteomics studies of various disease-related VDPs and for the discovery of new drug targets. Copyright

Highly selective fluorescent probe for vicinal-dithiol-containing proteins and in situ imaging in living cells

It pays to be direct: In a rapid and specific approach to the detection of vicinal-dithiol-containing proteins (VDPs), the use of a fluorescent probe (see picture) enabled the direct readout of fluorescence. This approach based on fluorescence polarization, electrophoresis, and the direct imaging of VDPs permits the noninvasive study of VDPs both in vitro and in living cells and offers insight into their potential roles in cell function.

More particularly, the invention provides for compounds of formula (I), and racemic and scalemic mixtures, diastereomers and enantiomers thereof: or an N-oxide, hydrate, solvate, pharmaceutically acceptable salt, prodrug or complex thereof, wherein Y, L, Z, W, M, Ra, Rb and Rc are as defined in the specification.

Carbonyl- and sulfur-containing analogs of suberoylanilide hydroxamic acid: Potent inhibition of histone deacetylases

Suberoylanilide hydroxamic acid (SAHA), an inhibitor of histone deacetylase, is used in clinical trials for a variety of advanced cancers. Twelve new analogs of SAHA were synthesized and tested as in vitro inhibitors of isolated histone deacetylases (HDACS) and in vivo inhibitors of interferon regulated transcriptional responses (a marker for HDAC activity). The analogs containing an α-mercaptoketone or an α-thioacetoxyketone were more potent than SAHA in both assays.

Exploring alternative Zn-binding groups in the design of HDAC inhibitors: Squaric acid, N-hydroxyurea, and oxazoline analogues of SAHA

Analogues of suberoylanilide hydroxamic acid (SAHA) were prepared by replacing the Zn-binding group with squaric acid, N-hydroxyurea, and 4-hydroxymethyl oxazoline units, also varying the length of the aliphatic chain. No inhibitory activity on HDAC was observed below 1.0 μM and no cytotoxic activity on different tumor cell lines was seen below 20.0 μM.
