Oleic acid is an unsaturated fatty acid found in significant quantities in various edible oils. Scientific studies have shown that oleic acid and its derivatives exhibit a variety of biological activities including antimicrobial and anticancer activities. In the present work, biotransformation of oleic acid was carried out initially using 27 different microbial strains. Extracts obtained from biotransformation with Alternaria alternata (clinical isolate) and Aspergillus terreus var. africanus (clinical isolate) were used in antimicrobial and anticancer activity studies. The in vitro antimicrobial activities of the extracts were evaluated against 9 different pathogenic microorganisms. The results indicated that the microbial extracts were more active than oleic acid itself and showed good inhibitory activity against all tested microorganisms. In in vitro anticancer activity studies, extract 2 obtained from biotransformation with Alternaria alternata exhibited notable anticancer activity against A549 cell line with an IC50 value of 62.5 μg/ml whereas positive control cisplatin showed an IC50 value of 43.5 μg/ml. The anticancer activity of extract 2 was also found to be selective according to its higher IC50 value (122.7 μg/ml) obtained against the healthy cell line, mouse embryonic fibroblasts, NIH3T3. Due to its anticancer effect, extract 2 is considered to participate in further research.

The aim of this study was to evaluate concentration-dependent antioxidant and anticancer activities of CA and RA in ethanol extracts of three different Oregano species (Origanum onites L., Origanum vulgare L., and Origanum vulgare ssp. hirtum). The study revealed the highest RA antioxidant activity in O. vulgare ssp. hirtum (9550±95 mmol/g) and the lowest in O. vulgare L. (2605±52 mmol/g) (p<0.05). The highest CA amount was present in O. onites L., which was 1.8 and 4.7 times higher (p<0.05) than in O. vulgare ssp. hirtum and O. vulgare L., respectively. The anticancer activity was evaluated on human glioblastoma (U87) and triple-negative breast cancer (MDA-MB231) cell lines in vitro. RA anticancer activity was negligible. CA and the extracts were about 1.5–2 times more active against MDA-MB231 cell line (p<0.05) compared to U87 cell line. The anticancer activities of three tested extracts were similar against U87 cell line (p>0.05) but they had different activities against MDA-MB231 cell line.

Due to the versatile application of plants the utilization of plants and their inferred substances builds up day by day for the revelation of new curative agents. Conocarpus erectus has placed in the family Combretaceae, in one of the two species of Conocarpus genus and ordinarily exists in tropical and subtropical regions of the world. In some countries it is used as folk medicine for fever, anemia, diabetes, catarrh, diarrhea and conjunctivitis. The current study was carried out to investigate the antibacterial and anticancer properties of the plant. The four defatted methanol extracts of C. erectus different parts (leaves, stems, fruits and bark) showed high antibacterial and anticancer activity even with small quantity of dose. Antimicrobial assay was used to check out the antibacterial activity against 6 bacterial strains Escherichia coli, Staphylococcus Aureus and Klebstella Pneumoniae.  The results show that gram positive bacteria show more sensitivity and zone of inhibition as compared to gram negative bacteria. For anticancer activity, MTT assay was performed on HepG2 cells for this purpose. Plant extorts show anticancer activity with a minute quantity. For phytochemical screening defatted methanol extract of Conocarpus erectus was subjected to the silica gel glass column go behind by (RP-HPLC–UV–ESI-MS). It contains phenol such as tannin and flavinoid as major component. Plant contain Ellagic acid; di-hexahydroxy diphenyl, Vascalgin isomer as foremost tannin component. Gallic Acid, Kaempferol on the base of mass spectra and time of retention. The extract of Conocarpus erectus (leaves, shoot, bark & fruit) parts shows high antibacterial, antioxidant and hepta-protective activities due to phenolic content. Tannin has high antibacterial activity than other compound. C.erectus is notable for its folkloristic curative potential. More in vivo and in vitro phytochemical studies are needed to use the plant for prevention and treatment of many diseases.

Abstract Background Ovarian cancer causes more deaths than any other cancer of the female reproductive system because there is no effective screening and most women are diagnosed at advanced stages. The probability of survival at 5 years is less than 30%, and the limitation is that it will not respond to chemotherapy protocol and surgery as well. Moreover, some evidence have shown potential anticancer properties of flavonoids, protective chemicals in plant foods, such as being an antioxidant, antiestrogenic, antiproliferative, and antiinflammatory. In this study, the anticancer activity of crude ethanol extracts of leaves from Adhatoda vasica was investigated. Results By the application of a cell-based assay, the LC 50 value of the A. vasica which showed anticancer effect was used for further studies. The cell line treated with LD 50 value of A. vasica extracts was observed for 0 h, 24 h, and 48 h to reveal the inhibition of the metastatic property in treated PA1 cells. The mRNA isolated from the teratocarcinoma PA1 cells treated with the A. vasica extract was further converted to cDNA and was amplified for the analysis of the p53 gene, p21 gene, and GAPDH gene expression. The expression in treated cells and the untreated control indicated the activity of the A. vasica extract against the ovarian cancer. Conclusion The present study suggested the antiproliferative and antimetastatic effects of medicinal plant A. vasica on PA1 cells.

The role of vitamin D is implicated in carcinogenesis through numerous biological processes like induction of apoptosis, modulation of immune system inhibition of inflammation and cell proliferation and promotion of cell differentiation. Its use as additional adjuvant drug with cancer treatment may be novel combination for improved outcome of different cancers. Numerous preclinical, epidemiological and clinical studies support the role of vitamin D as an anticancer agent. Anticancer properties of vitamin D have been studied widely (both in vivo and in vitro) among various cancers and found to have promising results. There are considerable data that indicate synergistic potential of calcitriol and antitumor agents. Possible mechanisms for modulatory anticancer activity of vitamin D include its antiproliferative, prodifferentiating, and anti-angiogenic and apoptic properties. Calcitriol reduces invasiveness and metastatic potential of many cancer cells by inhibiting angiogenesis and regulating expression of the key molecules involved in invasion and metastasis. Anticancer activity of vitamin D is synergistic or additive with the antineoplastic actions of several drugs including cytotoxic chemotherapy agents like paclitaxel, docetaxel, platinum base compounds and mitoxantrone. Benefits of addition of vitamin D should be weighed against the risk of its toxicity.

Background: Thiophene ring forms important building block in medicinal chemistry. Literature reveals that thiophene ring in combination with different groups shows different activity. By keeping these things in mind we have designed and synthesized a new series of amide and sulfonamide coupled thiophene. A series of novel substituted 3-sulfamoylbenzo[b]thiophene-4- carboxamide molecules containing sulfonamide and amide group were designed, synthesized and used for anti-proliferative activity study. Methods: The final compounds 16-36 were synthesized by using series of reactions comprising sulfonation, sulfonamide coupling, hydrolysis and peptide coupling. The yields of compounds 16- 36 are in the range of 90-98%. The structures of the synthesized compounds were elucidated and confirmed by 1H NMR, 13C NMR, LCMS and the purity was checked through HPLC analysis. The compounds were further tested for their in vitro anticancer activity against a series of cell lines A549, HeLa, MCF-7 and Du-145. Results: The intermediates 8-13, 15 and final compounds 16-36 were synthesized in good yields. The synthesized compounds were further tested for their anticancer activity and most of compounds showed moderate to good anticancer activity against all four cell lines. Conclusion: We have synthesized 21 compounds and were screened for anticancer activity against MCF-7, HeLa, A-549 and Du-145 cancer cell lines. Most of the compounds were active for tested cell lines with IC50 value in the range of 1.81 to 9.73 μM. The compounds 18, 19, 21, 25, 30, 31 and 33 are most active in cell line data with IC50 value in the range of 1.81 to 2.52 μM.

The fusion of 1,2,4-triazole and 1,3,4-thiadiazole rings results in a class of heterocycles compounds with an extensive range of pharmacological properties. A series of 1,2,4-triazolo[3,4-b]-1,2,4-thiadiazoles was synthesized and tested for its enzyme inhibition potential and anticancer activity. The results show that 1,2,4-triazolo[3,4-b]-1,2,4-thiadiazoles display potent anticancer properties in vitro against a panel of cancer cells and in vivo efficacy in HT-29 human colon tumor xenograft in CB17 severe combined immunodeficient (SCID) mice. Preliminary mechanistic studies revealed that KA25 and KA39 exhibit time- and concentration-dependent inhibition of Akt Ser-473 phosphorylation. Molecular modeling experiments indicated that 1,2,4-triazolo[3,4-b]-1,2,4-thiadiazoles bind well to the ATP binding site in Akt1 and Akt2. The low acute toxicity combined with in vitro and in vivo anticancer activity render triazolo[3,4-b]thiadiazoles KA25, KA26, and KA39 promising cancer therapeutic agents.

HDAC inhibitors (HDACis) have been developed as promising anticancer agents in recent years. In this study, we synthesized and characterized a novel HDACi, termed NBM-HD-1. This agent was derived from the semisynthesis of propolin G, isolated from Taiwanese green propolis (TGP), and was shown to be a potent suppressor of tumor cell growth in human breast cancer cells (MCF-7 and MDA-MB-231) and rat glioma cells (C6), with an IC50ranging from 8.5 to 10.3 μM. Western blot demonstrated that levels of p21(Waf1/Cip1), gelsolin, Ac-histone 4, and Ac-tubulin markedly increased after treatment of cancer cells with NBM-HD-1. After NBM-HD-1 treatment for 1–4 h, p-PTEN and p-AKT levels were markedly decreased. Furthermore, we also found the anticancer activities of NBM-HD-1 in regulating cell cycle regulators. Treatment with NBM-HD-1,p21(Waf1/Cip1)gene expression had markedly increased whilecyclin B1andD1gene expressions had markedly decreased. On the other hand, we found that NBM-HD-1 increased the expressions of tumor-suppressor genep53in a dose-dependent manner. Finally, we showed that NBM-HD-1 exhibited potent antitumor activity in a xenograft model. In conclusion, this study demonstrated that this compound, NBM-HD-1, is a novel and potent HDACi with anticancer activityin vitroandin vivo.
