Humic substances are effective in the suppression of delayed type hypersensitivity, rat paw
oedema, a graft‐versus‐host reaction and contact hypersensitivity in rats. They reduce the C‐…

New 7-chloroquinolinyl thiourea derivatives derived from the corresponding 4,7-dichloroquinoline
isothiocyanate were synthesized and evaluated for in vitro antimalarial and anticancer …

Two novel derivatives of clofazimine [3‐(p‐chloroanilino)‐10‐(p‐chlorophenyl)‐2,10‐dihydro‐2‐isopropylimino)phenazine]
and the tetramethylpiperidine (TMP)‐substituted phenazines…

The antiinflammatory activity of topically applied coal‐derived fulvic acids (called oxifulvic
acid) at 4.5% and 9% was compared with that of diclofene sodium at 1% and betamethasone …

… The viability of cells was determined by the MTT method, as described by van Rensburg
et al. Jurkat cells were the most sensitive, while the CoLo cells were the least sensitive to the …

Background: Often potentially good chemotherapeutic drugs find limited clinical use due to
the many negative medical and physical side-effects they may exhibit. To combat these …

Background: Oxidised ferrocenium compounds often possess antineoplastic activity. In
contrast, reduced ferrocene derivatives frequently only show activity if cell components can …

Erythromycin base and its 6-0-methyl derivative clarithromycin were actively accumulated
7.3 ± 1.2-fold and 9.2 ± 2-fold respectively by human neutrophils in vitro. The intraphagocytic …

The intra- and extracellular activities of 5 novel tetramethylpiperidine (TMP)-substituted
phenazines against Mycobacterium tuberculosis H37Rv (ATCC 27294) were determined and …

The ferrocene/ferricenium redox system plays a significant role in biological oxidation, reduction
and free‐radical reactions. Of particular interest are the findings of earlier investigations …
