Abstract

Rhodamine dye compositions and methods for detecting and/or delineating cancerous and precancerous epithelial tissue.

Description

Be used to detect epitheliomatous rhodamine diagnostic agent and diagnostic method
The present invention relates to novel diagnostic agent, be used to detect carcinous and epithelial tissue precancer.
According to a further aspect, the present invention relates to novel method, its be used for detecting and/or describe carcinous and/or precancer epithelial tissue.
The present invention relates to such diagnotor and agents useful for same thereof on the other hand, they especially can be used for the possible oral cancer patient of screening in the body, as the routine inspection of dentist or doctor physician or the part of program, for example regular dentistry or internal medicine inspection, tooth cleaning etc.
The present invention is relating in one aspect to such program and composition therefor thereof in addition, and they use than easier acquisition of the used stain of prior art program and/or synthetic more cheap Yu simpler and/or purer stain.
The present invention is in the body internal program and the compositions that relate in one aspect to a kind of like this stain of employing in addition, although prior art has opposite instruction, but this stain is enough nontoxic, so that by cleaning whole oral cavity and/or gargling and can be used.
Be used to detect the in-vivo diagnostic program that worsens anterior epithelium cornea damage, for example oral injury and oral cancer and adopt such stain compositions, the selected property ground of organizing that they are taken place because of abnormal development, hypertrophy, tumor and other active surface damages are unusual keeps, and these programs are known in the art.For example, adopt the program of fluorescein or fluorescein derivative to be disclosed among Chenz " Chinese stomatology magazine " (27:44-47 (1992)) and the Filurin (" stomatology " (Russia) 72:44-47 (1993)).These programs relate to and being coated with stain, under uviol lamp, with the naked eye check then, with detect selectivity fluorescigenic carcinous/precancer tissue.
Another kind of prior art program relates in the body cleans with blutene, is normal macroscopy then, to detect the tissue of all selectively stainings.Such program for example is disclosed in the United States Patent (USP) 4,321,251 of the United States Patent (USP) 5,372,801 of Tucci etc. and Mashberg.Toluidine blue has used many decades as vitro tissue pathology stain.It has become known metachromatic stain by this purposes, and is extremely pink the nuclear purple that is rich in DNA and RNA.When stain combined with nucleic acid or other acid cellular macromolecules, the inherent navy blue of blutene became purple or pink.Certainly, such dyeing depends on that stain enters inner subcellular structure, for example nuclear.Only with formaldehyde or other ruptured cell films but the reagent that does not destroy the general structure of cell " fix " tissue samples and can be easy to realize this entering.
Opposite with the mechanism that relates to external purposes, the dyeing oral cavity tissue is because it can the penetration cell wall and depends on mitochondrion in the blutene body, and it is longer that mitochondrion keeps the time ratio extracellular matrix components of stain.
The program of Mashberg relates to gargling with blutene solution cleans whole oral cavity, and water and acetic acid clean to remove not by stain carcinous or tissue reservation precancer then.After 10-14 days, directly, carry out tentative diagnosis then by the Mashberg program to suspecting that the position is coated with the blutene compositions.Tucci's ' 801 patent disclosure according to the employed improvement blutene of the general program compositions of Mashberg instruction.
Papazian " clinical and biology of gastroenterology " 9:16-22 (1985) has proposed a kind of body internal program, relates to the purposes of Lv Geer solution (Lugol ' s solution) (iodine) and blutene, is used for detecting simultaneously the esophageal carcinoma and last air flue digestive tract cancer.
Recently, the United States Patent (USP) 5,882,627 of Pomerantz discloses a class formation Ming Que De oxazine and a thiazine stain, and they generally can be used for the Mashberg diagnosis scheme.
Bemal etc. " cancer research " 43,716-720 (1983) disclose external optionally anticancer growth of rhodamine stain and kill cancer cell.The United States Patent (USP) 5 of Gaboury etc., 773,460 disclose rhodamine is preferentially kept by a lot of tumor cells, has proposed some rhodamine ester and can be used for the external smooth power inhibition of some tumor cell line, but pointed out that also general toxicity may limit its serviceability in chemotherapy.
Rhodamine is 2-(6-amino-3-imino group-3H-xanthene-9-yl) essence of Niobe and ion salt thereof, for example hydrochlorate, is pyridines lipophilic cation stain.General according to Mashberg's the disclosed scheme of ' 251 patent, be applied to epithelium by the part, then by normal macroscopy, it effectively selectivity differentiate and/or describe carcinous and precancer epithelial tissue.
The stain that is fit to be applied to epithelial tissue is preparation like this with the rhodamine compositions, with this stain and the pharmaceutically acceptable solvent that is fit to.Preferably, with the pH of the pharmaceutically acceptable buffer system adjusting rhodamine solution that is fit to, so that final solution is isoosmotic basically, the pH scope is approximately 2.5 to 7, is preferably 4.0-5.0.This can realize with acetic acid-sodium acetate buffer system.Other buffer systems that are fit to comprise citric acid-sodium citrate, or blended silicate system, for example citric acid-sodium phosphate etc.
Being used to the solvent of liquid rhodamine stain compositions of the present invention is provided is a kind of aqueous solvent.According to the present preferred embodiment of the present invention, that solvent comprises is pharmaceutically acceptable, just nontoxic, anergy is pure, ethanol for example.But such solvent can not disturb dyeing mechanism in perception ground, itself can not help stain to be reduced to the procrypsis form from the colour developing form yet.
If use, can add the stable correctives of other components of stain compositions, to improve the palatability of compositions as oral cavity " washing liquid ".
Preferably regulate rhodamine stain measuring to concentration in fluid composition and account for 1% of final composition weight greatly, but also can adopt higher concentration, lower concentration also be at least part effectively.Now, my preferential the employing contains the 0.5 stain compositions to about 3.5 weight % rhodamine components of having an appointment.
The compositions that is used for the inventive method is also contained in the present invention, and wherein by ' the 801 disclosed mode of patent comprises pharmaceutically acceptable oxidant to be similar to Tucci's, any procrypsis form that is present in the stain in the compositions is oxidized to the colour developing form.

Clinical effectiveness
The disclosed diagnosis scheme of ' 251 patent that utilizes Mashberg's, the clinical effectiveness of comparing embodiment 1 and 2 compositionss and the prepared blutene diagnosis reference composition (diagnostic control composition) of ' 801 patent according to Tucci's.
At first adopt TBO reference composition screening pathological change of oral cavity patient.After differentiating potential carcinous or precancerous lesion, water and embodiment 2 acetic acid washing liquids are cleaned repeatedly and are suspected the position, remove all TBO vestiges.
Use the testee of the patient of performance pathological change of oral cavity then as embodiment 1 rhodamine diagnosis composition.2-3cc rhodamine compositions is applied to the pathological changes mucous membrane surface, cleans with washed mixture and water then, to remove excessive rhodamine compositions.
The histological examination of embodiment 1 rhodamine diagnosis composition dyeing part tissue confirms, the rhodamine compositions at least differentiate with describe carcinous and precancer epithelial tissue on the same effective with blutene.
Embodiment 4
Repeat the program of embodiment 3, but gargle, be applied to oral mucosa, rather than directly be applied to suspection part, position by cleaning with test and reference composition.Obtain identical result.
My invention is open to the degree that makes those skilled in the art understand and to implement, and discloses preferred embodiment at present.
