Brine Shrimp Lethality Assay

The extracts of leaves of Combretum molle were tested against the larvae of Artemia salina, i.e. Brine Shrimp Lethality Test (BST) and Culexquinquefasciatus Say (filaria disease vector) i.e. Larvicidal Test, using crude ethanol, n-hexane, chloroform, ethyl acetate, and methanol extracts. The methanolic extract proved to be the most effective in inducing complete lethality at minimum doses both in the BST and the Larvicidal activity test. The LC50­ values obtained are 24.85 µg/ml and 0.4µg/ml respectively. The Bioactivity result was used to guide the column chromatography which afforded the pure compound ACM 2 which was not active in the BST with LC50 value of 1259 µg/ml but was active in the Larvicidal activity test with LC50 value 15.14 µg/ml.  ACM 2 was proposed to be N-heptadecyl-N-(8-octa-1, 3-diene-6-ynyl)amine (C25H44N).

Aims: Tinospora cordifolia is a herb used in the traditional folk medicine due to their health benefits. Studies reported the biochemical composition and some biological properties of the plant stem. The aim of the current study was to investigate the antimicrobial and cytotoxic properties from the extract of Tinospora cordifolia stem. Place and Duration of Study: The study was accomplished by eleven months in the Department of Pharmacy, University of Science and Technology Chittagong (USTC), Bangladesh.  Methodology: Presence of phytochemical constituents such as alkaloids, flavonoids and tannins, saponins were evaluated. Antimicrobial activity of the stem extract was assayed separately using an agar diffusion method against some gram negative and gram positive bacteria. The cytotoxic potential of the stem extract was evaluated by the Brine-Shrimp Lethality Assay mathod.  Results: The zone of inhibition formed by the methanolic extract in the antimicrobial assays was significant. In addition, cytotoxicity of the extract was found to be significant as compared to the standard gallic acid in Brine-Shrimp lethality assay. Conclusion: The methanolic extract of Tinospora cordifolia may possess significant antimicrobial property which requires more studies to isolate the specific bioactive compound for developing a new antimicrobial agent from this plant.

Starting Point

Many natural products could serve as the starting point in the development of modern medicines because of their numerous biological and pharmacological activities. However, some of them are known to carry toxicological properties as well. In order to achieve a safe treatment with plant products, numerous research studies have recently been focused on both pharmacology and toxicity of medicinal plants. Moreover, these studies employed efforts for alternative biological assays. Brine Shrimp Lethality Assay is the most convenient system for monitoring biological activities of various plant species. This method is very useful for preliminary assessment of toxicity of the plant extracts. Rapidness, simplicity and low requirements are several advantages of this assay. However, several conditions need to be completed, especially in the means of standardized experimental conditions (temperature, pH of the medium, salinity, aeration and light). The toxicity of herbal extracts using this assay has been determined in a concentration range of 10, 100 and 1000 µg/ml of the examined herbal extract. Most toxicity studies which use the Brine Shrimp Lethality Assay determine the toxicity after 24 hours of exposure to the tested sample. The median lethal concentration (LC50) of the test samples is obtained by a plot of percentage of the dead shrimps against the logarithm of the sample concentration. LC50 values are estimated using a probit regression analysis and compared with either Meyer’s or Clarkson’s toxicity criteria. Furthermore, the positive correlation between Meyer’s toxicity scale for Artemia salina and Gosselin, Smith and Hodge’s toxicity scale for higher animal models confirmed that the Brine Shrimp Lethality Assay is an excellent predictive tool for the toxic potential of plant extracts in humans.

This research was aimed to synthesize cinchonidine isobutyrate ester and conduct a preliminary assay for anticancer agent using cytotoxicity assay to Artemia salina Leach larva, or also known as brine shrimp lethality test (BSLT). Cinchonidine, a compound that has quinoline rings and quiniclidine ring, is a quinine analogue and stereoisomer of cinchonine. Cinchonidine is predicted to have anticancer activity. Synthesized ester was aimed to gain higher lipophilicity. Higher lipophilicity makes it easier for the compund to pass through cell membrane. The esterification process used DMAP as a catalyst, DCC as an activator, and isobutyric acid as a carboxilyc acid. Isobutyric acid is a type of short chained fatty acid that usually acts as an anticancer prodrugs. The product is identified by ESI-MS, FT-IR, 1H-NMR, dan 13C-NMR. Ester cinchonidine isobutyrate is gelatinous and colourless with yield of 21,77%. BSLT result showed that cinchonidine isobutyrate ester had LC50 value of 75.16 ppm which was more toxic than cinchonidine that had LC50 value of 99.2 ppm. It was proved that higher lipophilicity could increase pharmacology activity

Abstract: Isolation and cytotoxic activity of the β-carotene combination of Trigona honey and Namnam leaves extract (Cynometra cauliflora) were conducted. The urgency of isolating β-carotene compounds because of their known anticancer activity. Namnam leaves are macerated using methanol, then combined with Trigona honey. Fractionation and isolation of β-carotene in combination samples were conducted out by chromatography method. The β-carotene was analyzed using UV-Vis and FTIR spectrophotometer. The cytotoxic activity test was conducted by using the Brine Shrimp Lethality Test (BSLT) method with mortality analysis using Probit Analysis with SPSS v20 and Lethal Concentration 50 (LC50) as parameters. The result showed that the cytotoxic activity of Trigona honey after combination reached 36.6% with an LC50 value of 168.2 ppm, an increase from the Trigona honey sample (LC50 = 265.2 ppm) and Namnam leaves extract (LC50 = 196.12 ppm). The highest cytotoxic activity belongs to the n-hexane fraction (LC50 = 77.6 ppm). The best eluent for β-carotene isolation is petroleum ether. There was increased cytotoxic activity in isolates (LC50 of 22.85 ppm). Isolates were analyzed by UV-Vis and FTIR and compared with standards compound. FTIR analysis results showed that the isolates had functional groups of -CH3 (v 2850-2960 cm-1), -CH3 aliphatic (v 1350-1470 cm-1), C=C (v 2100-2350 cm-1 and 675-870 cm-1), and C-O (v 1000-1300 cm-1). Thus, the combination of Trigona Honey and Namnam leaf extract can be developed as an alternative chemopreventive agent.Abstrak: Isolasi dan aktivitas sitotoksik β-karoten kombinasi madu trigona dan ekstrak daun namnam (Cynometra cauliflora) telah dilakukan. Urgensi mengisolasi senyawa β-karoten karena telah diketahui adanya aktifitas antikanker. Daun namnam dimaserasi menggunakan metanol, untuk kemudian dikombinasikan dengan madu trigona. Fraksinasi dan isolasi β-karoten pada sampel kombinasi dilakukan dengan metode kromatografi. Kandungan senyawa β-karoten dianalisis menggunakan spektrofotometer UV-Vis dan FTIR. Uji aktifitas sitotoksik dilakukan dengan metode Brine Shrimp Lethality Test (BSLT) dengan analisis mortalitas menggunakan Probit Analysis dengan software SPSS v20 dan Lethal Concentration 50 (LC50) sebagai parameter. Hasil analisis menunjukkan bahwa aktivitas sitotoksik madu trigona setelah dikombinasikan mencapai 36,6 % dengan nilai LC50 sebesar 168,2 ppm, meningkat dari sampel madu trigona dengan (LC50 = 265,2 ppm), dan ekstrak daun namnam dengan (LC50 = 196,12 ppm). Aktifitas sitotoksik tertinggi dimiliki oleh fraksi n-heksana(LC50 = 77,6 ppm). Eluen terbaik untuk isolasi β-karoten adalah petroleum eter. Terjadi peningkatan aktifitas sitotoksik pada isolat hasil pemisahan (LC50 sebesar 22,85 ppm). Isolatdianalisis dengan UV-Vis dan FTIR dan dibandingkan dengan senyawa standar. Hasil analisa FTIR menunjukkan isolat memiliki gugus fungsi -CH3 (v 2850-2960 cm-1), -CH3 alifatik (v 1350-1470 cm-1), C=C (v 2100-2350 cm-1 dan 675-870 cm-1), dan C-O (v 1000-1300 cm-1). Dengan demikian, kombinasi Madu Trigona dan ekstrak daun namnam berpotensi untuk dikembangkan sebagai agen kemoprefentif alternatif.
