Molecular Engineering of Ultrabright Biomimetic NanoGhost for Site-Selective Tumor Imaging and Biodistribution.

Optically active ultrabright imaging agents are shown to delineate tumor location with deep tissue visualization in pre noclinical tumor models. NanoGhosts (NGs) particles are reconstructed from the cell membrane and integrated with organic fluorophores to attain ultra-brightness for solid tumor imaging. Moreover, the integration of amphiphilic and lipophilic molecules reveals structural characteristics of NGs (≈70 nm), which also alter their brightness.

Tongue and teeth hyperpigmentation in etoposide, prednisolone, vincristine, and cyclophosphamide regimen in the treatment of cutaneous lymphoma.

Cutaneous extranodal non-Hodgkin lymphoma is a rare cancer and chemotherapeutic agents like etoposide, vincristine and cyclophosphamide are the drug of choice, which rarely cause hyperpigmentation in skin and nails. However, herein we present a case of hyperpigmentation that was seen in tongue and even in teeth. The hyperpigmentation of the tongue and teeth occurred shortly after the initiation of chemotherapy.

Synthesis, Characterization, Antitubercular and Anti-Inflammatory Activity of New Pyrazolo[3,4-d]Pyrimidines.

Aims And Objective: Copious proinflammatory cytokines including TNF-α and IL-1β are involved in progression of inflammation in human body. Inhibition of signaling mediated by proinflammatory cytokines offer effective in the treatment of inflammatory diseases. The treatment of dreadful infectious disease mycobacterium tuberculosis still remains a challenge owing to resistance to multiple drugs hence an urgent need for newer drugs.

Synthesis and in vitro cytotoxicity studies of certain novel heterocycles derived from bis 1, 2, 4-triazoles and their DNA damage studies.

Synthesis and evaluation of cytotoxicity of a series of heterocyclic compounds derived from 1, 4-bis-(5- [hydrazinocarbonylmethylthio]-4-phenyl-1,2,4-triazol-3-yl) butane (1a-b) are described. The triazolo-triazoles (9-15) and thiadiazoles (16-18) were prepared from respective thiosemicarbazide intermediates (2-8). The Schiff bases (19-24) were prepared from (1a, b) by reacting with different carboxaldehydes in acetic acid medium.
