Abstract
W. tinctoria, an Indian herb Indrajao, has significant therapeutic potential. While studies have highlighted the anti-inflammatory potential of the leaves and bark of this plant, similar efficacy of the seed-pods remains unexplored. We demonstrate significant anti-inflammatory effects of the hexane fraction (Fr-B) of ethyl acetate extract of the seedpods in reducing lipopolysaccharide and palmitate mediated inflammation in RAW264.7 macrophages and HepG2 cells. GC-MS and NMR profiling of Fr-B revealed the existence of hexadecanoic acid, ethyl hexadecanoate, 9,12-octadecanoic acid, 9,12,15-octadecatrienoic acid, 9,12,15-octadecatrienoic acid ethyl ester, ethyl linoleate and octadecanoic acid ethyl esters.

Abstract
Concentrations of heavy metals (Cr, Cu, Fe, Mn, Ni, Pb, and Zn) accumulation were studied in the leaves of two medicinal plant species, namely Holarrhena pubescens and Wrightia tinctoria, from two industrial areas and a control area. Our comparison study revealed that industrialization significantly increased the accumulation of heavy metals in both plant species. A comparison study in control and industrial areas exhibited that heavy metal accumulation was higher in the industrially affected area than in the control area. Heavy metal concentration exceeded the permissible limit recommended by the WHO in both species of two industrial areas. However, both species accumulated the least heavy metal concentration in the control area. Biochemical investigation specifies that in response to heavy metal accumulation, both species increased the activity of hydrogen peroxide (H2O2), malondialdehyde content, the activity of enzymatic (superoxide dismutase and peroxidase) and nonenzymatic (ascorbic acid) antioxidant, but decreased the primary (soluble carbohydrate and total protein), secondary metabolites (phenol and flavonoid) content and free radical scavenging (DPPH) activity. This study indicates that industrialization potentially harms medicinal plants by reducing the efficacy of their medicinal property.

Abstract
Wrightia tinctoria stem proteases were partially purified for the first time through a non-chromatographic technique, three phase partitioning (TPP), to concentrate the milk clotting proteases. Various parameters like salt and solvent concentration that affect the partitioning of the protease were examined. Maximum recovery and purification fold of the protease activity were found in the interfacial phase (IP) with 60% ammonium sulphate and 1:1 crude enzyme to t-butanol. Optimum pH and temperature of the enzyme fraction were found to be 7.5 and 50 °C respectively. Inhibition studies revealed its serine nature. Non-denaturing PAGE, Zymography and 2D PAGE of IP revealed presence of three different caseinolytic proteases of molecular weights 95.62 kDa, 91.11 kDa and 83.23 kDa with pI 3.89, 5.45 and 5.43 respectively. Both aqueous and lyophilized form of IP were remarkably stable retaining complete activity at 4 °C for 3 weeks. Electrophoretic analysis of casein hydrolysate by IP at different incubation time indicated a time dependent substrate subunit specificity with hydrolysis of κ-casein commencing after 10 min followed by α and β caseins. This pattern was found similar to that by commercial vegetable coagulant, Enzeco®. Study details the effectiveness of TPP concentrated W. tinctoria proteases as a vegetable coagulant alternative in cheese making.

Abstract
OBJECTIVE Psoriasis is a chronic immune-mediated disorder of the skin. The disease manifests itself with red or silvery scaly plaques distributing over the lower back, scalp, and extensor aspects of limbs. Several medications are available for the treatment of psoriasis; however, high rates of remission and side-effects still persist as a major concern. Siddha, one of the traditional systems of Indian medicine offers cure to many dermatological conditions, including psoriasis. The oil prepared from the leaves of Wrightia tinctoria is prescribed by many healers for the treatment of psoriasis. This work aims to decipher the mechanism of action of the W. tinctoria in curing psoriasis and its associated comorbidities. DESIGN The work integrates various pharmacology approaches such as drug-likeness evaluation, oral bioavailability predictions, and network pharmacology approaches to understand the roles of various bioactive components of the herb. RESULTS This work identified 67 compounds of W. tinctoria interacting with 238 protein targets. The compounds were found to act through synergistic mechanism in reviving the disrupted process in the diseased state. CONCLUSION The results of this work not only shed light on the pharmacological action of the herb but also validate the usage of safe herbal drugs.

Abstract
A serine protease was purified from the leaves of Wrightia tinctoria by sequential flow through method comprising screening, optimization, ammonium sulfate precipitation, gel filtration and ion exchange column chromatography. The yield and purification fold obtained were 11.58% and 9.56 respectively. A single band of serine protease was visualized on SDS-PAGE and 2-D gel electrophoretic analyses were revealed with the molecular mass of 38.5 kDa. Serine protease had an optimum pH of 8.0 and was stable at 45°C with high relative protease activity. The addition of metal ions such as Mg2+ and Mn2+ exhibits a high relative activity. Serine protease had a potent antibacterial activity against both Gram-positive and Gram-negative bacteria. A 10 μg/ml of serine protease was tested against S. aureus, M. luteus, P. aeruginosa and K. pneumoniae which had 21, 20, 18 and 17 mm of zone of inhibition respectively. Serine protease from W. tinctoria degrades the peptidoglycan layer of bacteria which was visualized by transmission electron microscopic analysis.

Abstract
Wrightia tinctoria Roxb. (R.Br.) is an Ayurvedic remedy, ethnomedically used in the treatment of various ailments. The present work was carried out to evaluate the anticancer and antioxidant activity as well as total phenolic and phytochemical contents of W. tinctoria bark methanolic extract (WTBM) by high-performance liquid chromatography (HPLC)-diode array detector. Antiproliferative activity of WTBM was evaluated against MDA-MB-231 and MCF-7 cancer cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, colony formation, and Hoechst staining. In addition, the antioxidant potential was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and 2,2- azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical cation decolorization assay. Total phenolic content was assessed by Folin–Ciocalteu method. The results demonstrated that WTBM exhibited significant antiproliferative effect against MDA-MB-231 (IC50 = 88.9 ± 1.27 μg/ml) and MCF-7 (IC50 = 45.71 ± 7.74 μg/ml) cancer cells in time- and dose-dependent manner. WTBM significantly suppresses colony formation and induces apoptosis in both MDA-MB-231 and MCF-7 cells as evident by morphological assessment, clonogenic assay, and Hoechst staining. The total phenolic content of WTBM was found to be 30.3 gallic acid equivalent mg/g dry weight of bark extract while IC50 value for DPPH and ABTS radical scavenging activity was 72.2 ± 2.8 μg/ml and 45.16 ± 1.95 μg/ml, respectively. HPLC analysis showed the presence of gallic acid, rutin, and quercetin in WTBM. These findings demonstrated that WTBM significantly inhibited proliferation of breast cancer cells and induced apoptosis, suggesting the potential chemopreventive activity of W. tinctoria bark.

Abstract
Wrightia tinctoria R. Br. belongs to family Apocynaceae commonly called as Sweet Indrajao, Pala Indigo Plant, Dyer's Oleander. “Jaundice curative tree” in south India. Sweet Indrajao is a small, deciduous tree with a light gray, scaly smooth bark. Native to India and Burma, Wrightia is named after a Scottish physician and botanist William Wright (1740-1827). Sweet Indrajao is called dhudi (Hindi) because of its preservative nature. The juice of the tender leaves is used efficaciously in jaundice. Crushed fresh leaves when filled in the cavity of decayed tooth relieve toothache. In Siddha system of medicine, it is used for psoriasis and other skin diseases. Oil 777 prepared out of the fresh leaves of the plant has been assigned to analgesic, anti-inflammatory, and anti-pyretic activities and to be effective in the treatment of psoriasis. The plant is reported to contain presence of flavanoid, glycoflavones-iso-orientin, and phenolic acids. The various chemical constituents isolated from various parts of the plant are reported as 3,4-Seco-lup-20 (29)-en-3-oic acid, lupeol, stigmasterol and campetosterol, Indigotin, indirubin, tryptanthrin, isatin, anthranillate and rutin Triacontanol, Wrightial, cycloartenone, cycloeucalenol, β-amyrin, Alpha-Amyrin, and β-sitosterol, 14α-methylzymosterol. Four uncommon sterols, desmosterol, clerosterol, 24-methylene-25-methylcholesterol, and 24-dehydropollinastanol, were isolated and identified in addition to several more common phytosterols. The Triterpinoids components of the leaves and pods of Wrightia tinctoria also isolated.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Wrightia tinctoria R. Br. (Apocyanaceae) is a folk medicinal plant known to have immunomodulatory, anti-inflammatory and antihemorrhagic potential. Wrightia tinctoria latex is used for treatment of various clinical conditions including psoriasis, blisters, mouth ulcers, and extensively for topical application on fresh wounds to promote accelerated healing. AIMS OF THE STUDY To investigate the wound healing potential of Wrightia tinctoria latex proteases using a mouse model. MATERIALS AND METHODS Proteolytic activity of Wrightia tinctoria latex proteases (WTLP) was determined on various substrates (casein, gelatin and collagen (type-I and IV)). The thermal stability and the class of proteases present in WTLP were determined using heat treatment and specific protease inhibitors, respectively. Excision wound model in mice was used to evaluate the healing potential of WTLP application (twice daily, 10mg/kg). Neosporin, a standard drug, was used for comparison. The progression of healing was monitored using physical (wound contraction), biochemical (collagen content, catalase and MMP activity) and histological examinations. RESULTS WTLP contains thermostable serine proteases, which are completely inhibited by PMSF. WTLP showed strong caseinolytic, gelatinolytic and collagenolytic activity. The excision wound healing rate upon WTLP treatment was significantly higher than (>2-fold) the control group (49% vs. 18%, (**)p<0.01) on day 3 and throughout the study. PMSF pre-treated and heat denatured WTLP failed to promote wound healing. In addition, serial biochemical analysis of the granulation tissue demonstrated 1.5-fold more (2444 ± 100 vs. 1579 ± 121 µg/100mg tissue) hydroxyproline content and 5.6-fold higher catalase activity (16.7 ± 1.3 vs. 3 ± 0.3 units/mg) compared to controls. Further, the enhanced collagen content and matrix metalloproteinase activity correlated with wound contraction rate following WTLP and Neosporin treatment. Histological analysis on day 9 confirmed complete epithelialization, re-establishment of skin structure and accelerated wound healing following WTLP treatment. CONCLUSIONS The thermostable serine proteases of Wrightia tinctoria latex are directly involved in the wound healing process. Our findings provide a biochemical basis for the role of WTLP in the enhancement of wound healing. The study supports traditional topical application of Wrightia tinctoria latex on fresh wounds to promote accelerated healing.
