One-Pot Synthesis of Phosphinylphosphonate Derivatives and Their Anti-Tumor Evaluations.

ABSTRACT: This paper reports on the synthesis of new hydroxymethylene-(phosphinyl)phosphonates (HMPPs). A methodology has been developed to propose an optimized one-pot procedure without any intermediate purifications. Various aliphatic and (hetero)aromatic HMPPs were synthesized in good to excellent yields (53-98%) and the influence of electron withdrawing/donating group substitution on aromatic substrates was studied. In addition, the one-pot synthesis of HMPP was monitored by ³¹P NMR spectroscopy, allowing effective control of the end of the reaction and identification of all phosphorylated intermediate species, which enabled us to propose a reaction mechanism. Optimized experimental conditions were applied to the preparation of biological relevant aminoalkyl-HMPPs. A preliminary study of the complexation to hydroxyapatite (bone matrix) was carried out in order to verify its lower affinity towards bone compared to bisphosphonate molecules. Moreover, in vitro anti-tumor activity study revealed encouraging antiproliferative activities on three human cancer cell lines (breast, pancreas and lung).

One-pot synthesis, anti-tumor evaluation and structure-activity relationships of novel 25-OCH<sub>3</sub>-PPD derivatives.

Project description:Based on the fact that 25-OCH3-PPD, a natural ginsengenin isolated from the leaves of Panax ginseng, is a promising lead compound, novel 25-OCH3-PPD derivatives were synthesized to find more potent anti-tumor agents by a simple and facile synthetic method. These derivatives were classified into three types and screened for their cytotoxic activities against seven human cancer cell lines. Compared with 25-OCH3-PPD, compounds a5, a7, b5 and b7 exhibited higher anti-tumor activities on all tested cell lines with almost 5-fold to 15-fold increases. In particular, compound a7 showed the greatest cytotoxic activity against ?-2 cells (IC50 = 2.4 ± 0.4 ?M). The preliminary study on the mechanisms indicated that compound a7 could induce ?-2 cell apoptosis. Structure-activity relationships demonstrated that the carbon-carbon double bond at the C-20 position could enhance the antiproliferative activity. In conclusion, the novel derivatives a5, a7, b5 and b7 could be further studied as potential candidates for the treatment of cancer. This research provides a theoretical reference for the exploration of new antiproliferative agents.

One-Pot Synthesis of α-Alkyl Styrene Derivatives.

Project description:There is a significant need to develop more rapid and efficient routes to styrene derivatives, since they are extensively used in polymer sciences. This manuscript reports a one-pot synthesis of an array of α-alkyl styrene derivatives from readily available natural products (i.e., estragole and safrole). This method is regioselective, producing a rearranged adduct, under transition metal-free conditions. This methodology has broad nucleophile scope, even tolerating sterically hindered nucleophiles; it is general for carbon, nitrogen, oxygen, and sulfur nucleophiles.

One-Pot Synthesis of Four Chlorin Derivatives by a Divergent Ylide.

Project description:Chlorins have unique photophysical properties that are exploited in diverse biological and materials applications. De novo chlorin synthesis with specific exocyclic motifs can be challenging and many are not stable to photobleaching and/or oxidation. A facile approach to a stable synthetic chlorin with a fused N-methyl pyrrolidine uses cyclo addition of a sarcosine-based azomethine ylide on 5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)-porphyrin (TPPF20) is reported, but this approach has limitations. We report the synthesis of stable chlorin scaffolds starting with TPPF20 using a new glycine-based N-(hydroxymethyl)- N-methelenemethanideaminium ylide. Careful control of the 1,3-dipolar cycloaddition reaction allows a divergent use of the glycine derived ylide to yield four new chlorins, including the fused NH-pyrrolidine, two dimers, and the same N-methyl chlorin product from the sarcosine ylide reaction. The mechanism begins with the formation of a bis(hydroxymethyl)glycine, which then dehydrates and decarboxylates to form the active N-(hydroxymethyl)- N-methelenemethanideaminium ylide, which then reacts with TPPF20 to form a key N-(hydroxymethyl)-17,18-pyrrolidinyl-chlorin intermediate. Deformylation of this intermediate affords the (17,18-pyrrolidinyl)-chlorin, whereas a Cannizzaro-type reaction promotes a hydride attack to an imine chlorin cation to yield the N-methyl chlorin. The exocyclic NH-pyrrolidine provides a unique mode of attaching chiral moieties that avoids formation of diasteromers at the bridgehead carbons.

One-Pot Multicomponent Synthesis and Bioevaluation of Tetrahydroquinoline Derivatives as Potential Antioxidants, ?-Amylase Enzyme Inhibitors, Anti-Cancerous and Anti-Inflammatory Agents.

Project description:Mankind has always suffered from multiple diseases. Therefore, there has been a rigorous need in the field of medicinal chemistry for the design and discovery of new and potent molecular entities. In this work, thirteen tetrahydroquinoline derivatives were synthesized and evaluated biologically for their antioxidant, ?-amylase enzyme inhibitory, anti-proliferative and anti-inflammatory activities. SF8 showed the lowest IC50 of 29.19 ± 0.25 µg/mL by scavenging DPPH free radicals. SF5 showed significant antioxidant activity in total antioxidant capacity (TAC) and total reducing power (TRP) assays. SF5 and SF9 showed the maximum inhibition of ?-amylase enzyme i.e., 97.47% and 89.93%, respectively, at 200 µg/mL concentration. Five compounds were shortlisted to determine their anti-proliferative potential against Hep-2C cells. The study was conducted for 24, 48 and 72 h. SF8 showed significant results, having an IC50 value of 11.9 ± 1.04 µM at 72 h when compared with standard cisplatin (IC50 value of 14.6 ± 1.01 µM). An in vitro nitric oxide (NO) assay was performed to select compounds for in vivo anti-inflammatory activity evaluation. SF13 scavenged the NO level to a maximum of 85% at 50 µM concentration, followed by SF1 and SF2. Based on the NO scavenging assay results, in vivo anti-inflammatory studies were also performed and the results showed significant activity compared to the standard, acetylsalicylic acid (ASA).

Synthesis and Evaluations of Novel Apocynin Derivatives as Anti-Glioma Agents.

Project description:Apocynin (4-hydroxy-3-methoxyacetophenone) is a natural polyphenolic compound with multiple biological activities. In the present study, a series of apocynin derivatives were designed and synthesized. The in silico ADMET prediction, blood-brain barrier (BBB) penetration assay, anti-NADPH oxidase activity, reactive oxygen species (ROS) levels, and anti-glioma effects of these apocynin derivatives were evaluated. The anti-glioma mechanisms of candidate compounds were studied by ﬂow cytometer and Western blot. The results showed that D31 exhibited higher BBB penetration, increased ROS generations and significant anti-glioma effects both in vitro and in vivo. Further studies showed that D31 inhibited the activations of NF-κB pathway. Overall, our data demonstrated that D31 inhibited growth and induced apoptosis of glioma, which might be caused by ROS-related NF-κB activation. The current study suggested that D31 could be further explored for its potential use in anti-glioma therapy.

One-Pot Synthesis of Novel Thiazoles as Potential Anti-Cancer Agents.

Project description:Background:Thiazole and thiosemicarbazone derivatives are known to have potential anticancer activity with a mechanism of action related to inhibition of matrix metallo-proteinases, kinases and anti-apoptotic BCL2 family proteins. Materials and Methods:A novel three series of 5-(1-(2-(thiazol-2-yl)hydrazono)ethyl)thiazole derivatives were prepared in a one-pot three-component reaction using 2-(2-benzylidene hydrazinyl)-4-methylthiazole as a starting precursor. MS, IR, 1H-NMR and 13C-NMR were used to elucidate the structures of the synthesized compounds. Most of the synthesized products were evaluated for their in vitro anticancer screening against HCT-116, HT-29 and HepG2 using the MTT colorimetric assay. Results:The results indicated that compounds 4c, 4d and 8c showed growth inhibition activity against HCT-116 with IC50 values of 3.80 ± 0.80, 3.65 ± 0.90 and 3.16 ± 0.90 ?M, respectively, compared to harmine (IC50 = 2.40 ± 0.12 ?M) and cisplatin (IC50 = 5.18 ± 0.94 ?M) reference drugs. Also, compounds 8c, 4d and 4c showed promising IC50 values of 3.47 ± 0.79, 4.13 ± 0.51 and 7.24 ± 0.62 ?M, respectively, against the more resistant human colorectal cancer (HT-29) cell line compared with harmine (IC50 = 4.59 ± 0.67 ?M) and cisplatin (IC50 = 11.68 ± 1.54 ?M). On the other hand, compounds 4d, 4c, 8c and 11c were the most active (IC50 values of 2.31± 0.43, 2.94 ± 0.62, 4.57 ± 0.85 and 9.86 ± 0.78 ?M, respectively) against the hepatocellular carcinoma (HepG2) cell line compared with harmine (IC50 = 2.54 ± 0.82 ?M) and cisplatin (IC50 = 41 ± 0.63 ?M). The study also suggested that the mechanism of the anticancer action exerted by the most active compounds (4c, 4d and 8c) inside HCT-116 cells was apoptosis through the Bcl-2 family. Conclusion:Thiazole scaffolds 4c, 4d and 8c showed anticancer activities in the micromolar range and are appropriate as a candidate for cancer treatment.

Silibinin derivatives as anti-prostate cancer agents: Synthesis and cell-based evaluations.

Project description:This study aims to systematically explore the alkylation effect of 7-OH in silibinin and 2,3-dehydrosilibinin on the antiproliferative potency toward three prostate cancer cell lines. Eight 7-O-alkylsilibinins, eight 7-O-alkyl-2,3-dehydrosilibinins, and eight 3,7-O-dialkyl-2,3-dehydrosilibinins have been synthesized from commercially available silibinin for the in vitro cell-based evaluation. The WST-1 cell proliferation assay indicates that nineteen out of twenty-four silibinin derivatives have significantly improved antiproliferative potency when compared with silibinin. 7-O-Methylsilibinin (2) and 7-O-ethylsilibinin (3) have been identified as the most potent compounds with 98- and 123-fold enhanced potency against LNCaP human androgen-dependent prostate cancer cell line. Among 2,3-dehydrosilibinin derivatives, 7-O-methyl-2,3-dehydrosilibinin (10) and 7-O-ethyl-2,3-dehydrosilibinin (11) have been identified as the optimal compounds with the highest potency towards both androgen-dependent LNCaP and androgen-independent PC-3 prostate cancer cell lines. 7-O-Ethyl-2,3-dehydrosilibinin (11) was demonstrated to arrest PC-3 cell cycle at the G0/G1 phase and to induce PC-3 cell apoptosis. The findings in this study suggest that antiproliferative potency of silibinin and 2,3-dehydrosilibinin can be appreciably enhanced through suitable chemical modifications on the phenolic hydroxyl group at C-7 and that introduction of a chemical moiety with the potential to improve bioavailability through a linker to 7-OH in silibinin and 2,3-dehydrosilibinin would be a feasible strategy for the development of silibinin derivatives as anti-prostate cancer agents.
