1. Diacetate Naphthoquinone Derivatives Tethered to 1,2,3-Triazoles: Synthesis and Cytotoxicity Evaluation in Caco-2 Cells
Acetylated compounds prepared from naphthoquinones have been reported as antitumoral prodrugs. Exploring the synthetic versatility of the naphthoquinone and triazolic nuclei, herein we report a simple and efficient synthetic route to prepare a series of sixteen prodrugs prototype of 1,2,3-triazoles-naphthoquinodoic acetyl derivatives. The compounds 10a-10h a

2. COMPLEXOS DE PLATINA(II) CONJUGADO E ANÁLOGO A O-GLICOSÍDEOS: SÍNTESE, CARACTERIZAÇÃO ESTRUTURAL E ATIVIDADE ANTITUMORAL
The synthesis, characterization, cytotoxicity and antitumor activity of platinum(II) complexes coordinated to O-glycoside and analogous is reported. Through the acute toxicity tests, it was possible to fit the complexes into categories according to the OECD protocol. The cis-[PtCl2(C6H14S2O2)-κ2S] complex was classified in category 3 and the cis-[PtCl2(C26H

3. Evaluation of the immunomodulatory effect against splenocytes of Balb/c mice of biflorin obtained from Capraria biflora by a new isolation method
Abstract Biflorin (6,9-dimethyl-3-(4-methylpent-3-en-1-yl) benzo[de]chromene-7,8-dione) is a promising substance that has been increasingly studied in the past decades due to its diverse pharmacological properties (i.e. antitumor, antioxidant, antiinflamatory, antimicrobial activity etc.). Aiming the comprehension of its antitumoral activity we investigated

4. Physicochemical characterization and evaluation of in vitro and in vivo toxicity of goldenberry extract nanoemulsion
RESUMO: Nanoemulsão óleo/água (O/A) contendo extrato de goldenberry foi elaborada utilizando método de banho ultrassônico de alta energia. A caracterização físico-química da formulação foi realizada pela determinação do pH, diâmetro médio de gotas, índice de polidispersão (PDI) e potencial zeta. A toxicidade das nanoemulsões foi avaliada u

5. Hemolytic, anticancer and antigiardial activity of Palythoa caribaeorum venom
Abstract Background Cnidarian venoms and extracts have shown a broad variety of biological activities including cytotoxic, antibacterial and antitumoral effects. Most of these studied extracts were obtained from sea anemones or jellyfish. The present study aimed to determine the toxic activity and assess the antitumor and antiparasitic potential of Palythoa

6. A cytotoxic Petiveria alliacea dry extract induces ATP depletion and decreases β-F1-ATPase expression in breast cancer cells and promotes survival in tumor-bearing mice
Abstract Metabolic plasticity in cancer cells assures cell survival and cell proliferation under variable levels of oxygen and nutrients. Therefore, new anticancer treatments endeavor to target such plasticity by modifying main metabolic pathways as glycolysis or oxidative phosphorylation. In American traditional medicine Petiveria alliacea L., Phytolaccacea

7. LNO3 AND L3 Are Associated With Antiproliferative And Pro-Apoptotic Action In Hepatoma Cells
Abstract The identification of antitumoral substances is the focus of intense biomedical research. Two structural analogues of thalidomide, LNO3 and L3, are two synthetic compounds that might possess such antitumor properties. We evaluated the toxicological effects of these substances, including cytotoxicity, genotoxicity and induction of apoptosis in HTC ce

8. Estudo da atividade citotóxica, genotóxica e apoptótica de novos complexos de ouro (III) de fluorquinolonas frente às células B16-F10, K562 e A20 / Study of cytotoxic, genotoxic and apoptotic complex of new gold (III) of fluoroquinolones against B16-F10 cells, K562 and A20
O complexo de ouro K[Au(CN)2], por exemplo, foi introduzido na virada do século XX para o tratamento da tuberculose e logo após substituído pelos tiolatos de ouro (I), que foram usados nos anos 30 para o tratamento da artrite reumatóide. A exploração de complexos de ouro para uso como agente anticâncer foi iniciada na tentativa de se obter uma droga m

10. Development and characterization of PLGA nanocapsules of grandisin isolated from Virola surinamensis: in vitro release and cytotoxicity studies
The most studied phyto constituent isolated from Virola surinamensis (Rol. ex Rottb.) Warb., Myristicaceae, is the tetrahydrofuran neolignan grandisin, which exhibits a series of biological activities, including trypanocidal, larvicidal and antitumoral. Due to its extremely low solubility, additional studies, including in vivo investigations are challenged b

11. Tumor cytotoxicity of leucurolysin-B, a P-III snake venom metalloproteinase from Bothrops leucurus
Although it has been demonstrated that venoms and toxins from some snakes are able to influence the growth of tumor cells, few antitumoral compounds from Bothrops leucurus venom have been characterized. Leucurolysin-B (leuc-B) is a metalloproteinase class P-III isolated from B. leucurus which possesses an ECD-disintegrin domain. Both ECD-disentegrin and RGD-
