          Highlights

          The current study aims at exploring the bioactive molecules in Siddha Polyherbal Nilavembu Kudineer alleviating symptoms of Dengue/ Chikugunya.

          Editor’s Summary

          Nilavembu Kudineer is one of the thirty-two types of internal medicines described in the ancient Siddha system of medicine in south India which reduces fever and relieves body aches.

          Abstract

          Dengue is the most prevalent arthropod-borne viral diseases in terms of morbidity and mortality in the recent decade with the classic symptoms of high fever, headache as well as muscle and joint pain. Nilavembu Kudineer (NK) is one among the 32 types of internal medicines described in the ancient Siddha system of medicine in south India which reduces fever and relieves body aches. NK, a polyherbal formulation made up of eight traditional herbs in equal parts, is also recommended for prevention and management of all types of viral infections including Dengue/Chikugunya. Exploration of bioactive compounds in the plants is the primary step for the standardization and bioactivity screening of plants and formulations. So the current study aims at recording the chemical constituents and medicinal activities of each ingredient of NK. The anti-pyretic, anti-inflammatory, analgesic and immunostimulant effects of NK have been attributed to more than one ingredient in NK. The medicinal property of the NK can be also attributed to the combined effect of all phytochemicals present in these eight herbs. The current study encompasses the various chemicals and the activities of individual herbs but a thorough stereoscopic and chromatographic investigation is required to trace out the major phytochemical entities which are retained once the NK is prepared by the traditional methods.

          D-Limonene: safety and clinical applications.

          Jidong Sun (2007)
          D-limonene is one of the most common terpenes in nature. It is a major constituent in several citrus oils (orange, lemon, mandarin, lime, and grapefruit). D-limonene is listed in the Code of Federal Regulations as generally recognized as safe (GRAS) for a flavoring agent and can be found in common food items such as fruit juices, soft drinks, baked goods, ice cream, and pudding. D-limonene is considered to have fairly low toxicity. It has been tested for carcinogenicity in mice and rats. Although initial results showed d-limonene increased the incidence of renal tubular tumors in male rats, female rats and mice in both genders showed no evidence of any tumor. Subsequent studies have determined how these tumors occur and established that d-limonene does not pose a mutagenic, carcinogenic, or nephrotoxic risk to humans. In humans, d-limonene has demonstrated low toxicity after single and repeated dosing for up to one year. Being a solvent of cholesterol, d-limonene has been used clinically to dissolve cholesterol-containing gallstones. Because of its gastric acid neutralizing effect and its support of normal peristalsis, it has also been used for relief of heartburn and gastroesophageal reflux (GERD). D-limonene has well-established chemopreventive activity against many types of cancer. Evidence from a phase I clinical trial demonstrated a partial response in a patient with breast cancer and stable disease for more than six months in three patients with colorectal cancer.

            Antibacterial activities of flavonoids: structure-activity relationship and mechanism.

            Flavonoids are well known as antibacterial agents against a wide range of pathogenic microorganism. With increasing prevalence of untreatable infections induced by antibiotic resistance bacteria, flavonoids have attracted much interest because of the potential to be substitutes for antibiotics. In this review, the structure-relationship of flavonoids as antibacterial agents is summarized, and the recent advancements on the antibacterial mechanisms of flavonoids are also discussed. It is concluded that hydroxyls at special sites on the aromatic rings of flavonoids improve the activity. However, the methylation of the active hydroxyl groups generally decreases the activity. Besides, the lipopholicity of the ring A is vital for the activity of chalcones. The hydrophobic substituents such as prenyl groups, alkylamino chains, alkyl chains, and nitrogen or oxygen containing heterocyclic moieties usually enhance the activity for all the flavonoids. The proposed antibacterial mechanisms of flavonoids are as follows: inhibition of nucleic acid synthesis, inhibition of cytoplasmic membrane function, inhibition of energy metabolism, inhibition of the attachment and biofilm formation, inhibition of the porin on the cell membrane, alteration of the membrane permeability, and attenuation of the pathogenicity.

              Biological Activities of α-Pinene and β-Pinene Enantiomers

              The antimicrobial activities of the isomers and enantiomers of pinene were evaluated against bacterial and fungal cells. The agar diffusion test showed that only the positive enantiomers of the α- and β-isomers of pinene were active. The minimal inhibitory concentration (MIC) and minimal microbicidal concentration (MMC) of these monoterpenes were also determined, confirming that the positive enantiomers exhibited microbicidal activity against all fungi and bacteria tested with MICs ranging from 117 to 4,150 µg/mL. However, no antimicrobial activity was detected with the negative enantiomers up to 20 mg/mL. Time-kill curves showed that (+)-α-pinene and (+)-β-pinene were highly toxic to Candida albicans, killing 100% of inoculum within 60 min. By contrast, the bactericidal effect occurred after 6 h in methicillin-resistant Staphylococcus aureus (MRSA). In combination with commercial antimicrobials, ciprofloxacin plus (+)-α-pinene or (+)-β-pinene presented synergistic activity against MRSA whereas an indifferent effect against all fungi was detected when amphotericin B was combined with the positive enantiomers of pinene. The potential of (+)-α-pinene and (+)-β-pinene to inhibit phospholipase and esterase activities was also evaluated, and the best inhibition results were obtained with Cryptococcusneoformans. C. albicans biofilm formation was prevented with the MIC concentration of (+)-α-pinene and twice the MIC value of (+)-β-pinene. Finally, the cytotoxicity of the positive enantiomers of pinene to murine macrophages was evaluated, and 250 µg/mL of (+)-α-pinene and (+)-β-pinene reduced the cell viability to 66.8% and 57.7%, respectively.
