Indian cherry (Cordia dichotoma Forst.) is a medicinally important plant widely consumed as an indigenous remedy for several ailments in the India. Although it is widely used plant by the population, there are no studies on root proving these medicinal claims. The present study was designed to investigate antimicrobial, antimycobacterial and antioxidant activities of Cordia dichotoma Forst. roots and in silico biological activities prediction using PASS. Methanolic extract was prepared and further fractions were obtained by liquid–liquid partitioning. Agar well difusion assay and disc difusion method were selected for antimicrobial activity. Antimycobacterial activity was estimated against Mycobacterium tuberculosis. For antioxidant activity, DPPH and hydrogen peroxide (H2O2) radical scavenging assay were employed. All the tested samples exhibited diverse pattern of sensitivity for tested strains. The value of MIC, MMC and MIC index showed that P. vulgaris and K. pneumonia were the most sensitive for ME and CF, whereas A. fumigates and V. myditis were sensitive to CF and AF. Microorganism susceptible index was 100 for P. vulgaris and K. pneumonia bacteria, and A. fumigates and V. myditis fungi. CF exhibited best activity against M. tuberculosis with lowest MIC of 30 mg/ml and highest activity index of 0.85. Dose dependent antioxidant activity was observed in both the assay. This data provides evidence that Cordia dichotoma Forst. roots have potent antibacterial, antimycobacterial, antioxidant, and moderate antifungal activity and a potential cure for infectious diseases like tuberculosis.
Synthetic Route for New (Z)-5-[4-(2-Chloroquinolin-3-yl) Methoxy]benzylidinethiazolidine-2,4-diones
Jawale, Dhanaji V.,Pratap, Umesh R.,Mane, Ramrao A. Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.7
Synthetic route has been developed for the synthesis of new (Z)-5-[4-(2-chloroquinolin-3-yl) methoxy]benzyl-idinethiazolidine-2,4-diones (6a-h) starting from 2-chloro-3-hydroxymethyl quinolines (2a-h). The hydroxy methyl quinolines on tosylation yielded (3a-h). Condensation of the tosyl intermediates with 4-hydroxy benzaldehydes has been carried in DMF in presence of $K_2CO_3$ and obtained 4-quinolinyl methoxy benzaldehydes (4a-h). Conveniently Knoevenagel condensation of quinolinyl methoxy benzaldehydes (4a-h) and 2, 4-thiazolidinedione (5) has been carried in PEG-400 in presence of L-proline and obtained better yields of the titled compounds (6a-h).

A convenient synthetic route has been developed to synthesize 5-(4-((2-phenylthiazol-4-yl) methoxy)phenyl)- 3-(4-sustituted phenyl)pyrazolines (5a-f) and 5-(4-((2-phenylthiazol-4-yl)methoxy)phenyl)-3-(4-substituted phenyl)isoxazolines (6a-f) starting from 2-phenyl-4-chloromethylthiazole (1). The chloromethylthiazole (1) was first condensed with 4-hydroxy benzaldehyde (2) for obtaining 4-((2-phenylthiazol-4-yl)methoxy)benzaldehyde (3). Claisen-Smidth condensation of 4-((2-phenylthiazol-4-yl)methoxy)benzaldehyde (3) and acetophenones has been carried in alkaline alcohol and obtained 3-(4-((2-phenylthiazol-4-yl)methoxy)phenyl)-1-(4- substituted phenyl)prop-2-en-1-ones (4a-f). The cyclocondensation of 2-propen-1-ones has been first time carried separately with hydrazine hydrate and hydroxylamine hydrochloride in aqueous micellar tetradecyltrimethylammonium bromide (TTAB) medium for getting the titled heterocycles with good to excellent yields.
