Heteroarotinoids inhibit head and neck cancer cell lines in vitro and in vivo through both RAR and RXR retinoic acid receptors

A class of less toxic retinoids, called heteroarotinoids, was evaluated for their molecular mechanism of growth inhibition of two head and neck squamous cell carcinoma (HNSCC) cell lines SCC-2 and SCC-38. A series of 14 heteroarotinoids were screened for growth inhibition activity in vitro. The two most active compounds, one that contained an oxygen heteroatom (6) and the other a sulfur heteroatom (16), were evaluated in a xenograph model of tumor establishment in nude mice. Five days after subcutaneous injection of 107 SCC-38 cells, groups of 5 nu/nu mice were gavaged daily (5 days/week for 4 weeks) with 20 mg/kg/day of all-trans-retinoic acid (t-RA, 1), 10 mg/kg/day of 6, 10 mg/kg/day of 16, or sesame oil. After a few days, the dose of t-RA (1) was decreased to 10 mg/kg/day to alleviate the side effects of eczema and bone fracture. No significant toxic effects were observed in the heteroarotinoid groups. All three retinoids caused a statistically significant reduction in tumor size as determined by the student t-test (P < 0.05). Complete tumor regression was noted in 3 of 5 mice treated with t-RA (1), 4 of 5 mice treated with 16, 1 of 5 mice treated with 6, and 1 of 5 mice treated with sesame oil. Reverse transcriptase polymerase chain reaction (RT- PCR) was used to determine that the expression levels of RARalpha, RXRalpha, and RXRbeta were similar in the two cell lines, while RARbeta expression was higher in SCC-2 over SCC-38, and RARgamma expression was higher in SCC-38 over SCC-2. Receptor cotransfection assays in CV-1 cells demonstrated that 16 was a potent activator of both RAR and RXR receptors, while 6 was selective for the RXR receptors. Transient cotransfection assays in CV-1 cells using an AP-1 responsive reporter plasmid demonstrated that t-RA (1), 6, and 16 each inhibited AP-1-driven transcription in this cell line. In conclusion, the growth inhibition activity of the RXR-selective 6 and the more potent growth inhibition activity of the RAR/pan-agonist 16 implicate both RARs and RXRs in the molecular mechanism of retinoid growth inhibition. Moreover, the chemoprevention activity and the lack of toxicity of heteroarotinoids demonstrate their clinical potential in head and neck cancer chemoprevention. Do you like my blog?

Process development of the synthetic route to sulamserod hydrochloride

Sulamserod hydrochloride is a potent S-HT4 receptor antagonist and was a clinical candidate for the treatment of gastrointestinal disorders. Process development of the fairly long synthetic route (12 linear, 14 overall steps) was undertaken. Process improvements were highlighted by aromatic chlorination choices in making dichlorobenzodioxan 2 and acetylaminochloroketone 7, a transfer hydrogenation reducing a nitro group and simultaneous aromatic dechlorination without ketone reduction to give aminoketone 5, and use of the potential mutagenic iodosulfonamide 14 to make quaternary salt 11. The chemistry was scaled-up into pilot plant reactor vessels to produce multikilogram amounts of Sulamserod hydrochloride suitable for drug development.

New semi-synthetic analogs of oleuropein show improved anticancer activity in?vitro and in?vivo

Oleuropein is a glucosylated seco-iridoid present in olive fruits and leaves. Due to its broad spectrum of biological activities, including anticancer properties, oleuropein has attracted scientific attention for the past 20 years. The promising antiproliferative activity of an olive leaf extract enriched in oleuropein against a series of human cancer cell lines, prompted us to proceed with the semi-synthesis of 51 analogs of oleuropein. Following their initial screening against the estrogen receptor negative breast cancer cell line SKBR3, 7 analogs were shown to display significant cytotoxicity and were further tested against 6 additional solid tumor-derived and leukemic cell lines. The analog with the most promising antitumor activity (24) was selected for more detailed studies. 24 was non-toxic to peripheral blood mononuclear cells derived from healthy blood donors when tested at concentrations close to its half maximal inhibitory concentration. In vivo administration of 24 in melanoma-bearing mice resulted in reducing tumor size in a dose-dependent manner and in inducing anti-melanoma-reactive immune responses. Our results suggest that analog 24, emerging from the initial structure of oleuropein, represents a promising lead structure for further optimization.

Novel azanaphtoquinone compounds with aromatic amino moiety: Synthesis, structural characterization, and antimicrobial features

New azanaphtoquinone compounds with aromatic moiety were synthesized and their structures were defined by Fourier transform infrared, 13C NMR, 1H NMR and mass spectra. The activities of synthesized azanaphthoquinones as antimicrobial agents against three strains of Gram-positive, four strains of Gram-negative and as well as against three strains of fungi were also investigated. Compound 3d showed eight times greater antibacterial activity against the most sensitive organism being S. epidermidis with a MIC value of 1.22 mug/mL than the reference antimicrobial compound Cefuroxime (MIC = 9.8 mug/mL). For compound 3c, the antibacterial activity against S. epidermidis and S. aureus was equal to that of Cefuroxime and Cefuroxime-Na, respectively. The antibacterial activity of the compounds 3c and 3d were two times stronger against E. faecalis than the reference antimicrobial compound Amikacin. The results obtained in this study revealed that newly synthesized compounds 3c, 3d, and 3e are effective in treating infectious caused by especially Gram-positive bacteria have developed multiple resistances to antibiotics and are favorable structures in designing novel antimicrobial agents.

1,2,3-Dithiazoles-new reversible melanin synthesis inhibitors: A chemical genomics study

A chemical genomic screen of an in-house library of small molecule heterocycles was carried out using Xenopus laevis embryos. This led to the identification of N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-4-methoxyaniline (1c), which elicits loss of pigmentation in melanophores and the retinal pigment epithelium (RPE) of developing embryos, independent of the developmental stage of initial exposure. The phenotype was reversible, since pigmentation returned upon compound removal while analysis of neural crest cell markers (Pax7) and melanophore markers (Dct/Xtrp2) revealed that both neural crest precursors and fully differentiated melanophores were present in the dithiazole 1c treated embryos. A subsequent focused structure-activity relationship (SAR) study identified the more active dithiazole 4-benzyloxy-N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-aniline (1l) and the need for a chlorine substituent at the dithiazole C-4 position. Both the initial chemical genomic screen and the focused SAR study highlighted the toxicity of (dithiazolylidene)aminoazines, and also of methoxyaniline (anisidine) analogues that hosted strong electron-withdrawing or electronegative substituents or acidic hydroxyl groups on the anisidine moiety. This study suggests that 1,2,3-dithiazoles can act as reversible melanin synthesis inhibitors, revealing a new biological activity for this class of compounds. The inhibition of melanin synthesis is medically relevant as a potential treatment for pigmentation disorders such as melasma.
