The in vitro anti-denaturation effects induced by natural products and non-steroidal compounds in heat treated (immunogenic) bovine serum albumin is proposed as a screening assay for the detection of anti-inflammatory compounds, without the use of animals, in the early stages of the drug discovery process / Los efectos de la anti-desnaturalización in vitro inducida por productos naturales y compuestos no esteroidales en la albúmina sérica bovina (inmunogénica) tratada con calor, se proponen aquí como ensayo de pesquizaje para la detección de compuestos inflamatorios sin el uso de animales en las etapas tempranas del proceso de descubrimiento del medicamento

ABSTRACT
There are emerging ethical issues with regards to the use of animals in the early stages of drug discovery for anti-inflammatory and degenerative diseases from natural products using the activity-directed isolation pathways when many compounds (eg > 100) are present in the crude extract or fraction and are to be tested. The above-mentioned is the main reason for proposing the use of the in vitro anti-denaturation (stabilization) effects of heat treated (immunogenic) bovine serum albumin (BSA) as an assay. Current methods used for detecting and isolating a wide range of anti-inflammatory compounds in the early stages of the drug discovery process utilize a large number of animals. When BSA is heated and is undergoing denaturation, it expresses antigens associated to Type III hyper-sensitive reaction and which are related to diseases such as serum sickness, glomerulonephritis, rheumatoid arthritis and systemic lupus erythematosus. Thus, the assay that is being proposed should be applicable to the discovery of drugs for treating the above mentioned diseases and others, once the compounds stabilize the denaturation process.
RESUMEN
Actualmente surgen problemas éticos en relación con el uso de animales en las etapas tempranas del descubrimiento de medicamentos anti-inflamatorios y contra enfermedades degenerativas, a partir de productos naturales, usando vías de aislamiento dirigido por actividad, cuando muchos compuestos están presentes (p.ej. > 100) en la fracción o extracto crudo, y deben ser probados. Lo anterior representa la razón principal para proponer el uso de los efectos de la anti-desnaturalización (estabilización) in vitro de la albúmina sérica bovina (inmunogénica) tratada con calor (ASB) como ensayo. Los métodos corrientes usados para detectar y aislar una amplia gama de compuestos anti-inflamatorios en las etapas tempranas del proceso de descubrimiento del medicamento, utilizan un gran número de animales. Cuando la ASB es calentada y sometida a un proceso de desnaturalización, expresa antígenos en relación con la reacción hipersensitiva de tipo III, relacionada a su vez con enfermedades tales como la enfermedad del suero, la glomerulonefritis, la artritis reumatoide, y el lupus sistémico y eritematoso. De este modo, el ensayo que aquí proponemos debe ser aplicable al descubrimiento de medicamentos para el tratamiento de las enfermedades anteriormente mencionadas y otras, una vez que los compuestos estabilicen el proceso de desnaturalización.
