Design, synthesis and biological evaluation of novel 2,4-disubstituted quinazoline derivatives targeting H1975 cells via EGFR-PI3K signaling pathway

In order to find new and highly effective anti-tumor drugs with targeted therapeutic effects, a series of novel 4-aminoquinazoline derivatives containing N-phenylacetamide structure were designed, synthesized and evaluated for antitumor activity against four human cancer cell lines (H1975, PC-3, MDA-MB-231 and MGC-803) using MTT assay. The results showed that the compound 19e had the most potent antiproliferative activity against H1975, PC-3, MDA-MB-231 and MGC-803 cell lines. At the same time, compound 19e could significantly inhibit the colony formation and migration of H1975 cells. Compound 19e also arrested the H1975 cell cycle in the G1 phase and mediated cell apoptosis, promoted the accumulation of ROS in H1975 cells. Furthermore, compound 19e exerted antitumor effect in vitro by reducing the expression of anti-apoptotic protein Bcl-2 and increasing the pro-apoptotic protein Bax and p53. Mechanistically, compound 19e could significantly decreased the phosphorylation of EGFR and its downstream protein PI3K in H1975 cells. Which indicated that compound 19e targeted H1975 cell via interfering with EGFR-PI3K signaling pathway. Molecular docking showed that compound 19e could bind into the active pocket of EGFR. Those work suggested that compound 19e would have remarkable implications for further design of anti-tumor agents.

A catalyst-free method for the synthesis of 1,4,2-dithiazoles from isothiocyanates and hydroxylamine triflic acid salts

A catalyst-free method for the preparation of 1,4,2-dithiazoles is developed by reactions of isothiocyanates with hydroxylamine triflic acid salts. This reaction achieves C-S, C-N, and S-N bond formation, and a range of products are obtained in moderate to good yields. The obvious feature is using shelf-stable hydroxylamine triflic acid salts as a N source to synthesize heterocycles under mild conditions.

NaOH-promoted one-pot aryl isothiocyanate synthesis under mild benchtop conditions

In this work, we have established a green synthesis of aryl isothiocyanates promoted by the low-cost and readily available NaOH from aryl amines and carbon disulfide in a one-pot procedure. The developed protocol features no extra desulfurating reagents and mild benchtop conditions, in which NaOH serves as both the base and the desulfurating reagent to decompose the dithiocarbamate intermediate. Fourteen examples of aryl amines bearing electronic neutral, rich and poor substituents, as well as benzylamine, have proved to be compatible substrates in the developed method to furnish the corresponding isothiocyanates. The reaction has been performed on a gram scale to further demonstrate its synthetic utility. Compared to the reported base-promoted synthesis of aryl isothiocyanates that requires the use of special equipment, such as the ball mill or the microwave reactor, the simplicity in operation and scalability enables this method to efficiently access a variety of aryl isothiocyanates.

Synthesis of isothiocyanates using DMT/NMM/TsO? as a new desulfurization reagent

Thirty-three alkyl and aryl isothiocyanates, as well as isothiocyanate derivatives from esters of coded amino acids and from esters of unnatural amino acids (6-aminocaproic, 4-(aminomethyl)benzoic, and tranexamic acids), were synthesized with satisfactory or very good yields (25–97%). Synthesis was performed in a “one-pot”, two-step procedure, in the presence of organic base (Et3 N, DBU or NMM), and carbon disulfide via dithiocarbamates, with 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium toluene-4-sulfonate (DMT/NMM/TsO? ) as a desulfurization reagent. For the synthesis of aliphatic and aromatic isothiocyanates, reactions were carried out in a microwave reactor, and selected alkyl isothiocyanates were also synthesized in aqueous medium with high yields (72–96%). Isothiocyanate derivatives of L-and D-amino acid methyl esters were synthesized, under conditions without microwave radiation assistance, with low racemization (er 99 > 1), and their absolute configuration was confirmed by circular dichroism. Isothiocyanate derivatives of natural and unnatural amino acids were evaluated for antibacterial activity on E. coli and S. aureus bacterial strains, where the most active was ITC 9e.

Synthesis and antitumor activity of novel pyridazinone derivatives containing 1,3,4-thiadiazole moiety

A series of novel pyridazinone derivatives containing the 1,3,4-thiadiazole moiety were synthesized and characterized by 1H NMR, 13C NMR, spectroscopies HRMS and IR. Among them, the structure of compound 5c (2-(Tert-butyl)?4-chloro-5-((5-((2-ethylphenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One) was unambiguously confirmed via single crystal X-ray diffraction analysis. The inhibitory activity of all the target compounds against MGC-803 and Bcap-37 was determined by MTT assay, with doxorubicin (the inhibition rates were 95.5 ± 0.4% and 95.7 ± 1.0% respectively) as a control. The preliminary results showed that the inhibitory activity of compound 5n (2-(Tert-butyl)?4-chloro-5-((5-((3-fluorophenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One) was superior to the others. The inhibition rates of MGC-803 and Bcap-37 cells were 86.3 ± 2.2% and 92.3 ± 0.6% at a concentration of 10 μmol/L, respectively. The preliminary structure-activity relationship showed that when the 2-position of the benzene ring was substituted by a methyl group, such as compound 5j (2-(Tert-butyl)?4-chloro-5-((5-((2,3-dimethylphenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One), it exhibited good anticancer activity on MGC-803 cells. Besides, introducing fluorine, chlorine, or trifluoromethyl group onto the benzene ring, such as compound 5 m (2-(Tert-butyl)?4-chloro-5-((5-((4-(trifluoromethoxy)phenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One), displayed good anticancer activity on MGC-803 and Bcap-37 cells.

Inhibitors of the Diadenosine Tetraphosphate Phosphorylase Rv2613c of Mycobacterium tuberculosis

The intracellular concentration of diadenosine tetraphospate (Ap4A) increases upon exposure to stress conditions. Despite being discovered over 50 years ago, the cellular functions of Ap4A are still enigmatic. If and how the varied Ap4A is a signal and involved in the signaling pathways leading to an appropriate cellular response remain to be discovered. Because the turnover of Ap4A by Ap4A cleaving enzymes is rapid, small molecule inhibitors for these enzymes would provide tools for the more detailed study of the role of Ap4A. Here, we describe the development of a high-throughput screening assay based on a fluorogenic Ap4A substrate for the identification and optimization of small molecule inhibitors for Ap4A cleaving enzymes. As proof-of-concept we screened a library of over 42, 000 compounds toward their inhibitory activity against the Ap4A phosphorylase (Rv2613c) of Mycobacterium tuberculosis (Mtb). A sulfanylacrylonitril derivative with an IC50 of 260 ± 50 nM in vitro was identified. Multiple derivatives were synthesized to further optimize their properties with respect to their in vitro IC50 values and their cytotoxicity against human cells (HeLa). In addition, we selected two hits to study their antimycobacterial activity against virulent Mtb to show that they might be candidates for further development of antimycobacterial agents against multidrug-resistant Mtb.

Synthesis and biological evaluation of terminal functionalized thiourea-containing dipeptides as antitumor agents

A series of antitumor agents based on terminal functionalized dipeptide derivatives containing the thiourea moiety were synthesized and evaluated for antiproliferative activity using a panel of cancer cell lines, and the effects and mechanism of apoptosis induction were determined. These compounds exhibited significant selectivity to different cancer cell lines with IC50 values at micromolar concentrations. In particular, compound I-11 appeared to be the most potent compound, with an IC50 = 4.85 ± 1.44 μM against the NCI-H460 cell line, at least partly, by the induction of apoptosis. Mechanistically, compound I-11 induced the activation of caspase-12 and CHOP, which triggered apoptotic signalling via the ROS-dependent endoplasmic reticulum pathway and arrested the cell cycle at the S phase. Thus, we concluded that dipeptide derivatives containing the thiourea moiety terminally functionalized by electron-withdrawing substituents may be potential antitumor agents for further investigation.

Design, synthesis and in vitro evaluation of novel ursolic acid derivatives as potential anticancer agents

A series of novel ursolic acid (UA) derivatives modified at the C-3 and the C-28 positions were designed and synthesized in an attempt to develop potential antitumor agents. The in vitro cytotoxicity were evaluated against five cancer cell lines (MGC-803, HCT-116, T24, HepG2 and A549 cell lines) and a normal cell (HL-7702) by MTT assay. The screening results indicated that some of these target compounds displayed moderate to high levels of antiproliferative activities compared with ursolic acid and 5-fluorouracil (5-FU), and exhibited much lower cytotoxicity than 5-FU, indicating that the targeted compounds had selective and significant effect on the cell lines. The induction of apoptosis and affects on the cell cycle distribution of compound 6r were investigated by acridine orange/ethidium bromide staining, Hoechst 33258 staining, JC-1 mitochondrial membrane potential staining and flow cytometry, which revealed that the antitumor activity of 6r was possibly achieved through the induction of cell apoptosis by G1 cell-cycle arrest. Western blot and qRT-PCR (quantitative real-time PCR) experiments demonstrated that compound 6r may induce apoptosis through both of intrinsic and extrinsic apoptosis pathway.
