In reaction to the expanding predominance of diabetes mellitus, curcumin nanoparticles stacked on carboxymethyl cellulose (CMC) composite were effectively synthesized, characterized, and examined utilizing UV/Vis and FTIR spectroscopy combined with transmission electron microscopy (TEM). The bioactivity of curcumin (Cur), carboxymethyl cellulose (CMC), and curcumin nanoparticles stacked with carboxymethyl cellulose (CUR-CMC) was tried through atomic docking approval as an α-amylase and α-glucosidase inhibitor. The conclusion illustrated that the curcumin-supported CMC is more potent than CUR itself self the validation presented is compared with acarbose as a reference molecule and then CUR-CMC can presented as promising in curing hyperglycemia by decreasing the absorption of glucose.

Orotic acid esters and several N-arylhydrazones derivatives were synthesized and evaluated for their stem cell proliferation potential with human stromal stem cells (hMSCs) which was never studied before. Some of the derivatives exhibit convincing upregulation of proliferation which is believed to be due to substitution on the aromatic ring.

T. A simplified synthetic protocol was adopted for the preparation of the six novel cyclo-pentapeptide candidates of the structure cyclo-(m-phthaloyl)-bis-[L-Phe -Gly/Sar]-L-Lys–X, where X = COOMe (9a,b), COOH (10a,b) and NHNH2 (11a,b). The potential cytotoxicity (IC50, μg/mL) for cyclo-pentapeptides (9a,b), (10a,b), (11a,b) and doxorubicin® asreference drugs, is assayed against eight cell lines of human cancer namely; mamillary MCF-7 and T47D, hepatic HEPG2, colon HCT116, cell line of cervix HELA, larynx HEP2, Prostate PC3, and gut Caco. Cyclo-[m-phthaloyl chloride-bis-(L-phalanine-sar)-L-Lys]-COOH 10b was proved as cytotoxically more potent than doxorubicin against most of the screened cell lines. It can be inferred that the proposed molecular structural characteristics associated with cytotoxicity in these m-phthaloyl-bridged cyclopeptides appear noteworthy and hold promise as potential candidates for further exploration as novel anticancer agents. Molecular dynamics simulation studies of 10b into the binding site of Human Epidermal Growth Factor Receptor tyrosine kinase exhibited the highest MM-GBSA value (-16.59 kcal/mol).

Some new derivatives of substituted-4(3H)-quinazolinones were synthesized and evaluated for theirin vitroantitumor and antimicrobial activities. The results of this study demonstrated that compound5yielded selective activities toward NSC Lung Cancer EKVX cell line, Colon Cancer HCT-15 cell line and Breast Cancer MDA-MB-231/ATCC cell line, while NSC Lung Cancer EKVX cell line and CNS Cancer SF-295 cell line were sensitive to compound8. Additionally, compounds12and13showed moderate effectiveness toward numerous cell lines belonging to different tumor subpanels. On the other hand, the results of antimicrobial screening revealed that compounds1,9and14are the most active againstStaphylococcus aureusATCC 29213 with minimum inhibitory concentration (MIC) of 16, 32 and 32 μg/mL respectively, while compound14possessed antimicrobial activities against all tested strains with the lowest MIC compared with other tested compounds.In silicostudy, ADME-Tox prediction and molecular docking methodology were used to study the antitumor activity and to identify the structural features required for antitumor activity.

In the title compound, C(26)H(21)N(3)O(3)S, the quinazolinyl group is essentially planar [r.m.s. deviation for the 10 non-H atoms = 0.057 Å]. The isoindoline-1,3-dione group is linked by an SCH(2)CH(2) chain to the pyrimidinyl C atom that lies between the two N atoms. Also, the phenyl group is linked by a CH(2)CH(2) chain at the N atom adjacent to the carbonyl group. This results in a conformation with these substituents lying to either side of the central quinazolinyl unit, with the former being approximately parallel [dihedral angle = 4.93 (7)°], and the phenyl group being inclined [dihedral angle = 71.61 (9)°] to the central quinazolinyl fused-ring system. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by C-H⋯O inter-actions, involving all three carbonyl-O atoms, and π-π inter-actions occurring between the pyrimidinyl and isoindole-benzene rings [inter-centroid distance = 3.5330 (13) Å].

In the title compound, C(6)H(10)N(2)O(2)·H(2)O, the imidazole ring is essentially planar, with a maximum deviation of 0.012 (2) Å. In the crystal, mol-ecules are connected via N-H⋯O and O-H⋯O hydrogen bonds, forming a supra-molecular tape along the a axis.
