3-(3-Methyl­phen­yl)-2-thioxo-1,3-thia­zolidin-4-one

In the title compound, C10H9NOS2, the dihedral angle between the rhodanine (2-thioxo-1,3-thia­zolidin-4-one) and 3-methyl­phenyl rings is 83.30 (3)°. The H atoms of the methyl group are disordered over two set of sites with an occupancy ratio of 0.58 (3):0.42 (3). In the crystal, the mol­ecules inter­act by way of C—H⋯π and C=O⋯π inter­actions

5-[(E)-(2,6-Dichloro­benzyl­idene)amino]-2-hy­droxy­benzoic acid

There are two geometrically different mol­ecules in the asymmetric unit of the title compound, C14H9Cl2NO3. The 5-amino-2-hy­droxy­benzoic acid units [r.m.s. deviations of 0.0323 and 0.0414 Å] and 2,6-dichloro­benzaldehyde groups [r.m.s. deviations of 0.0285 and 0.0226 Å] are roughly planar and oriented at dihedral angles of 11.69 (13) and 83.12 (6)° in the two mol­ecules. An intra­molecular O—H⋯O hydrogen bond completes an S(6) ring motif in each mol­ecule. The two mol­ecules form dimers with each other through inter­molecular O—H⋯N and C—H⋯O hydrogen bonds, completing an R 2 2(8) ring motif. The dimers are inter­linked via inter­molecular O—H⋯N and C—H⋯O hydrogen bonds, forming polymeric sheets

Phenyl N-(2-methyl­phen­yl)carbamate

In the title compound, C14H13NO2, the aromatic rings attached to the O and N atoms make dihedral angles of 62.65 (9) and 38.28 (11)°, respectively, with the central carbamate group. The benzene rings are oriented at a dihedral angle of 39.22 (10)°. In the crystal, a very weak C—H⋯π inter­action occurs

Phenyl piperidine-1-carboxyl­ate

In the title compound, C12H15NO2, the dihedral angle between the benzene ring and the basal plane of the piperidine ring (which is in a chair conformation) is 49.55 (8)°. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds and very weak C–H⋯π inter­actions

2-{[(E)-1,3-Benzodioxol-5-yl]methyl­idene­amino}­benzoic acid

In the title compound, C15H11NO4, the dihedral angle between the aromatic rings is 23.8 (2)° and an intra­molecular O—H⋯N hydrogen bond generates an S(6) ring. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network

3-Acetyl-1-(3-chloro­phen­yl)thio­urea

In the title compound, C9H9ClN2OS, the 3-chloro­phenyl and acetyl­thio­urea fragments are oriented at a dihedral angle of 62.68 (5)°. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. Mol­ecules are linked into dimers via a cyclic R 2 2(8) motif of N—H⋯S hydrogen bonds. These dimers are further connected through C—H⋯S inter­actions, completing an R 2 2(12) motif, into chains along [010]

Morphological characterization, phytochemical profile, and cytotoxic and insecticidal activities of diverse parts of Bryophyllum pinnatum (Lam.)

Purpose: To standardize Zakham-e-Hayat (Bryophyllum pinnatum Lam.) as well as determine its cytotoxic and insecticidal activity. Methods: Different parts of the plant (flowers, young leaves, old leaves and stem) and different solvents, viz, methanol, ethyl acetate and n-hexane were used for the extraction. Morphological characterization (macroscopic and microscopic), phytochemical screening for primary and secondary metabolites, and thin layer chromatography (TLC) using various solvent systems, namely, methanol/chloroform (MeOH/CHCl3), n-hexane/methanol/chloroform (n-hexane/MeOH/CHCl3), methanol/chloroform/water (MeOH/CHCl3/H2O), n-hexane/chloroform (n-hexane/CHCl3), n-hexane/ethyl acetate (n-hexane/EtOAc) were carried out. Fourier transform infrared spectroscopy (FTIR) was also performed. In addition, the extracts were evaluated for their cytotoxic and insecticidal activities. Results: The methanol fraction of the young leaves had 50% lethal dose (LD50) of 28.46 µg/mL while the ethyl acetate fraction of young and old leaves showed significant cytotoxicity at LD50 of 0.13 µg/mL and 142.68 µg/mL respectively. On the other hand, n-hexane fraction was inactive. The methanol fraction of the flower revealed the presence of carbohydrates, the ethyl acetate fraction showed the presence of carbohydrates and amino acids, while the n-hexane fraction showed the presence of carbohydrates as primary metabolites. Furthermore, alkaloids, flavonoid, saponins and resins were present in the methanol fraction, flavonoid and alkaloids in the ethyl acetate fraction, and alkaloids and resins in the n-hexane fraction as secondary metabolites. Conclusion: Methanol and n-hexane fractions of Bryophyllum pinnatum have some safe bioactive compounds which may exhibit potential health benefits

Phenyl N-cyclo­hexyl­carbamate

In the title compound, C13H17NO2, the dihedral angle between the benzene ring and the basal plane of the cyclo­hexyl ring is 49.55 (8)°. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds, forming chains propagating in [010]
