IS PENICILLIN A PHOTOSENSITIZING AGENT?

Archives of Dermatology, 1945
It is a well known fact that penicillin therapy produces few reactions. Urticaria seems to be the most common cutaneous reaction. In this report the possibility is suggested that penicillin acts as a photosensitizing agent. Photodermatitis of vegetable origin has already been well studied.1It is due in most instances to external contact of the patient

Eradication of Acinetobacter baumannii by photosensitized agents in vitro

Journal of Photochemistry and Photobiology B: Biology, 1998
The photodynamic effects of photosensitizers on Acinetobacter baumannii were studied. These Gram negative bacteria have recently been implicated in various infections, mainly acquired in hospitals. They have outstanding characteristics of multidrug high resistance to antimicrobial agents. The best photodynamic effect was obtained when A.

Cutaneous photosensitivity diseases induced by exogenous agents

Journal of the American Academy of Dermatology, 1995
Cutaneous photosensitivity diseases may be idiopathic, produced by endogenous photosensitizers, or associated with exogenous photosensitizers. Those caused by exogenous agents include phototoxicity, photoallergy, and the exacerbation or induction of systemic disorders in which photosensitivity is a prominent clinical manifestation. Phototoxic disorders

Photosensitizers as virucidal agents.

Journal of photochemistry and photobiology. B, Biology, 1993
The photosensitizer, benzoporphyrin derivative monoacid ring A (BPD-MA) has been studied regarding its ability to destroy enveloped viruses in blood and blood products when activated by light. Its maximum wavelength of absorption (690 nm) has proven useful in terms of activation of the photosensitizer in materials containing red blood cells ...

SULFANILAMIDE: A PHOTOSENSITIZING AGENT OF THE SKIN

Journal of the American Medical Association, 1937
In spite of the intensive use of sulfanilamide in the last year as a chemotherapeutic agent in beta-hemolytic streptococcus infections, clinical reports have noted a relatively low incidence of untoward reactions. Our observations of more than 300 patients in the erysipelas wards of Bellevue Hospital (service of Dr.

[Exogenous photosensitizing agents].

La Revue du praticien, 1992
The frequent use of remedies either in topical or systemic form has led to a rising number of photosensitizations. The different cutaneous manifestations of exogenous photosensitizers e.g. phototoxicity and photoallergy, are described. We treat the most important agents of these reactions and lay stress upon the patient's interview and the phototesting

A carbohydrate-linked hypericinic photosensitizing agent

Monatshefte für Chemie - Chemical Monthly, 2008
With respect to an enhanced solubility under physiological conditions, a carbohydrate-containing hypericin-based second-generation photosensitizer was prepared. Its photochemical properties were tested by means of the light-sensitized destruction of bilirubin IXα to be even better than those of the parent compound hypericin.

GABAergic agents as anticonvulsants in baboons with photosensitive epilepsy

Neuroscience Letters, 1984
GABAergic agents have been evaluated for acute anticonvulsant activity in baboons, Papio papio with photosensitive epilepsy. The potent GABAA agonists muscimol and THIP are proconvulsant. (-)Baclofen, 2 mg/kg suppresses myoclonic responses; higher doses facilitate EEG paroxysmal activity.

Porphyrins as Antimicrobial Photosensitizing Agents

2013
The emergence of microbial resistance to many of the major classes of antimicrobial drugs is becoming an increasing problem in the clinic and environmental areas. As such, the discovery of drugs with novel modes of action will be vital to meet the threats created by the emergence of resistance.
